Bit of a long shot but does anyone have pictures/drawings/schematics Of the gun below?
Tim look at this thread on PST -

Is this it ?, but on a different trail...
cheers
Cheers for that 
Yes its the Geb version I'm after with the split trail, the 2nd link is the standard version. Since posting I've managed to find some reasonable pictures and some info on dimensions but a schematic would be a gopdsend, so many details particularly on the chasis that are unclear from the photo's.
Think thats more the finnish original train rather than a gebirgs version
May have kept original wood parts to save weight hauling it up.
Whilst it is true the Gebirgs used a lot off captured mountain guns I believe this split trail version was German, specifically designed for Gebirgs, could be taken down to 10 loads for carrying on horse/mules etc but believe they were manufactured in Dusseldorf.
weren't they even given designations depending on the number of horses it took them to be moved like the "pac 8" was an 8 horse gun etc.

Give me a big enough hammer and a place to stand and I could fix the world.
i'll kill a man in a fair fight or if i think he's going to start a fair fight or over a woman or.......
a problem shared is a problem halved ,but an advantage shared is no advantage at all
if a job's not worth doing then its certainly not worth doing well
As above, it is a standard 75mm LeIG on a special carriage. I think for airsoft purposes it doesn't need to be bob on (or are you doing a model of one?).
I have been fortunate enough to play with a real 75mm LeIG in the artillery shed at Shrivenham, and although it can easily be manhandled by one man on flat going (unlike the ammo), I would sure hate to carry one of those up a mountain. I presume the mountain gun could be disassembled, most of them could.

Yes designed to come apart for ease of transportation by man or mule. I thought it would be a good choice for airsoft artillery as the high trajectory would allow it to fire 2 stage mortar rounds 
What a brilliant idea!

I'd had exactly that same though Tim there was a thread a good while ago discussing this very thing;

I never got around to building it though but I reckon your the man to make it happen Tim

We need artillery - it's a Fuhrer directive! Go for it, Tim!
You've got nothing to ein, zwei, drei, vier
Ha ha, had not seen that thread as I wasnt on the scene back then but just goes to show there's no such thing as an original idea at least when it comes to WW2 airsoft, you veterans have already thought off/tried everything 
Funnily enough I had also been planning on doing a nebelwerfer, firing crow scaring rockets ignited by a firework ignition system. However as I've come all over Gebirgs at the moment this seemed a better Idea especially as it should strip down into something maneageable to fit in the back of my van. Sourced some wheels for it just waiting to get paid and will make a start on the carraige
Excellent, I guess the wheels are the hardest thing to source, the rest of the carriage is just three big bits of wood.
The main gun assembly and recoil tube are also very boxy, much easier to make than a 105 
Go for it Tim. Of course this means we'll all have to go out and buy artillery waffenfarbe now (although I dimly recall that regimental infantry guns were crewed by infantry).

Great idea Tim . You can count on me for first crew volunteer!
Nice one Tim Gavin (Dadio) and I had been toying with a similar idea of a 20mm flak auto cannon (As used in Saving Pte Ryan but with a gun shield) firing BB`s

Wheels are the easy part if you are doing an early or gebirgsjager version, loads of decorative wagon wheels on ebay.
For the later version, 16" space saver spares are just the job! Again loads on ebay.

Yes Ebay wagon wheels are the plan
Been going through the photo's and drawings I have found so far, I have good information on the barrel/breech, recoil block, trail legs, 2 part gun sheild and even the optics if I chose to make a mock up of them. What I dont have is any clear idea of the gubbins between the wheels Of course as Martin has said it doesn't have to be that accurate and if the rest of it looks the part I could probably be forgiven for going for construction in that area that is simply practical for making a working airsoft gun.
I think it would be nice to replicate the breach mechanism, I believe Josh has a breech plate on his mortars and puts the round in a case to absorb the detonation? Are there any legal issues with having a breech?
Also the elevating mechanism could be a problem, it will need to be some sort of screw jack worm gear device 
And Gordon/Gav go for the AA gun, I had been toying with the idea myself
Good to know we have plenty of volunteers for crew, but as this will take a while dont rush out and buy waffenfarbe yet.
I used a car scissor jack with a lathe wheel attached to give elevation adjustment on the 25 pounder I built. This worked well and I will probably do the same on one or more of my new projects. (I am building purely for airsoft and so my builds just need to be reasonable facsimiles. I have only basic tools (drill and jigsaw) but hope to do a pretty good job of a Pak 40, a Nebelwefer and a 37mm anti tank gun. I have the wheels sorted after weeks of hovering on Ebay.)
Ah thats useful to know, utilising a car jack had occured to me but did not know how practical it would be, perhaps you can show me what you have done at Spilamberto
I tried a few pulley systems but failed. So I fitted a cross member below the breech and attached the scissor jack to that. The breech was attached to the top of the jack with a cord to allow for any lateral movement. The Lathe wheel was an ebay job that I managed to fix in place on the Jack. To be fair, it is not a great job as it was an afterthought. The Jack needs to be securely fixed in place and the lathe wheel also must not wobble. I hope to do better on the next jobs, though they may not actually have working elevation. As for gubbins. I went around a car boot sale looking for anything that looked the part. I fitted a hand brake lever and a few other bits and pieces to the rear to make it look the part. I was lucky with one set of wheels as it came with an ancient mangle that has turning wheels and gears that I can use to dress one of them. Once I break through the rust that is.
