Hi I'm new to the forum have an interest in WW2 Weapons. I have an AGM MP40 that has broken just in front of the trigger guard 
now I'm guessing this part is going to be hard to source second hand or even harder to repair ? The metal can't be welded or can it ? Or is it a case of clean up and JB weld or some similar epoxy type of repair ? Hopefully someone here has experience of repairing this stuff ......, Thanks in advance Wes.
Hi Wesbro, put up some pictures of the problem, without a doubt there’s someone on here that can either give advice, or fix it for you.

I can't pull the pics off my tablet to show them ?
I use an iPad, I do on occasion have a problem uploading pic’s, but most of the time they load straight up. Somewhere on the forum there is a “ how to “ on the subject, basically go to attachments and follow the instructions.
That part is basically the gearbox mount, if you remove the side plastics there should be another two screws in there holding the front broken piece. Epoxy glue won’t help you with this, I would suggest a steel plate replacement with a jiggle in it, to fit over, and up to the trigger guard. Then drill, thread to 3mm and use short countersunk screws just in front of the said trigger guard. This, done properly, could be shaped and the screws filled in and over, and re-sprayed probably only to the depth of a few millimetres, and you wouldn’t even notice it.
Here’s a pic of an original piece.
Yes thats it. Do you mean like thin sheet shaped around it drilled tapped screwed and filled ?
You say “thin sheet” that implies to me, tin sheet. You’ll need at least 2mm thick steel plate to get any strength of support to the piece, you may even have to shape it round the trigger guard itself, if there’s not enough “ meat” on the original part.
For that part to have broken in the first place, I reckon that must have been dropped onto hard surface. Probably due to not putting the gun together properly after a battery change.
If I were doing it I'd discard the front bit that broke off and has the screws up into the gearbox and make a copy in steel but longer to extend back above the trigger guard bit , I'd cut away metal from what's left of the trigger guard part to allow the extra length of the steel plate and put counter sunk screws in from the top of the new steel plate down into the trigger guard , you'd have a virtually invisible repair that's fairly simple to do with basic hand tools ,a drill ,saw , a file and a tapp to cut the threads .

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
Here’s a sketch of my first thoughts, to replace the broken piece, but depending on what’s left to screw to, I did mention it may have to go round onto the trigger guard.
That's great, thanks, I'll source some scrap ally from work and try that idea. Sounds the best way to fix it to be honest. If I could get hold of the whole. Body as a replacement I would but it seems spare parts are a tad hard to get hold of.
