Stg 44 AEG improvement/customisation

There was here a topic on weathering of Stg 44 from AGM. It was very good work and idea. But the main problem with this replica in comparison to the real one - the safety buttom and fire selector witch remained untouched. Looking carefully into the AGM Stg and germen dokumentation I found the solution. It needs some more worktime spent but the effect, I believe, is worth it.
Below is a pictorial "How to" presentation. In original GB obly the selector plate needs some minor modification. The rest is related to the left "grip" plate. Reshaping the grip plate contour - it cannot be done other way as the grip plate is the part of all panel. Than the new rotating selector switch is to be made and fake safety button too.
Main tools - Dremel, files, small cylindrical metal bars (or lathe) amd finally a "liquid steel" epoxy putty - ready made or home made from regular epoxy glue and metal fillings. I prefer a plasticine-like form as it does not flow and can be preformed before hardening.

Finally (it is related to the first AGM releases) - the replacement of the crucial bolt connecting buttstoct with receiver from rubber O-ring based to the spring one (as in original and second versions of AGM product).
My approach to the early bakelite appearance is basic layer of semi-glossy chocolate brown and a thin spray (a mist) of matt black when brown is still wet. It fits very well to all gun's grips (MP-38, MP-40, P-38) made before ora at the beginning of WWII.

To give more flavour I would recommend the use of different appearance and colour of grips on the receiver grip and handle as well as different left and right parts. The rationale is simple. The shortage of resin, using different amount of filler wooden sawdust and various manufacurers resulted in these variety of colour and pattern observed on guns from the (near) end of war.
