Based on my “recent” post history it seems I complete a project every 2-3 years, but I think this one may be my longest running. I started this project, I want to say back in 2003-04, I could search through my post history and maybe find some of the old stuff I posted back then. Fortunately, you could still get SPAS parts, at the time, but if I recall even then they were getting scarce, and Humbrol was still making Brown Bess(still have one almost full jar after this too!) Tokyo Marui released their metal AEG Thompson so I knew I had to make this build.

Using the Bapty photos I created CAD files to make the 10 hole barrel vent and adjustable stock. Sold sets of them to fund the rest of the project. Basically got everything done except the wiring and painting. So. It’s been in a semi complete state ever since. One day builds always take longer than a day right?

The adjustable stock locks in three positions via a spring loaded bolt that mounts through the receiver of the Thompson and drops into three notches cut into the slide channel on the stock itself. It’s surprisingly secure.

A few weeks ago I decided that I was never going to get around to machining my own magainze base or grenade launcher end cap, so I picked those up from SD Studios, to finally complete this build.

I can’t remember who made the cast resin shrouds but I made all the smaller plates and fittings from sheet aluminum. Painted everything Brown Bess, weathered the aluminum parts by beating them up a little and some silver paint here and there for the shrouds. The whole gun was weathered basically with some gun oil and dirty hands grabbing it around the magazine well and carry handle, etc. I finished it off with black and stainless hardware. I feels good to see it the correct color after it being OD green for many years.

I’m pretty sure the counter was made by Hyperdyne systems. After sitting so long in various boxes and through multiple moves, the solder joints on the board were a little bad and I wouldn’t light up all the way. Resoldered every connection on the back of the board and I was back in business. The counter counts from 99 to 95 when you insert the magazine, and counts down when the trigger is pulled. I added a magnetic switch in the circuit to activate when inserting the magazine, wired it into the aeg switch to activate when you pull the trigger, then added a micro switch on the side to turn the whole thing off when it’s in my display cabinet. I’ve seen some of the newer systems like blastcore and others that have Pulse Rifle kits, but honestly just wanted to get this one done! It would be nice to add a little sound board inside one day to make it little more lively.

The airsoft gun is not currently wired to function, because this is going to be a static display prop, but it would be easy enough to wire it again for a battery if I ever decided I want to.

Dean, this is fantastic... Are you on Facebook at all - this group may be of interest:

 
Really appreciate the kudos everyone! I’m so happy to have it done finally and it turned out just as I hoped. It’s definitely the favorite of my collection!
 
Very cool! Awesome, infact! What did you use for the GL? Still need to get around to mine.. Got all the metal parts for mine except for an airsoft 870..

Thanks!

I don’t remember exactly what brand of 870 I used. It has a plastic housing with metal internals and was too thick to fit inside the SPAS cage so I had to take the left side off to make it fit. My main want was that it have a chrome “bolt” and use shells so I could cycle them through it. The shells ended up being a lot smaller than real 12 gauge shells so my machined M40 grenades wouldn’t fit anyway. That would have meant making mini M40s specifically for it so I abandoned that idea. I have an old resin M40 that I’m going to paint and stick it in the opening so it’s at least visible when you work the action.
 
NICE!!!
I'm pretty sure I'm one of those original 10 people that got in on your metal vent and stock run! I also used one of the TM Thompsons and MIM kit for the rest, it was from Jose's run that he did way back when....

Are you my twin? One of my builds is the old MIM with a metal airsoft Thompson but, I jsut found the 10 hole vent today. Im saving it for my all metal live fire PR. IMHO, the MIM shrouds are the most accurate shouds out there. The latest Spat Cave PR is right there also (solid resin).

Dean O, great job on the build. You have inspired me to bust open one of my BB tins and repaint mine.

lol, I always wondered if the MIM shrouds and other parts were recasts of the small run by SD Studios. I think he had made a couple with demilled Thompsons, that came in an awesome travel case, J-hyphen had (has?) one. It all happened at a similar time here on the board. MIM is known for outsourcing their kits - the rocketeer pack and helmet they used to sell were from ACME.
