My dad wrote this in another forum 2-3 years ago...He will be out of contact for a while but I thought you could be interested in his project...Thanks, AZ jr.

I looked for one of those OLD Thompson machine guns during the late 70's and finally found one in brand new condition back in the mid 90's, the new guns are not as appealing as these old Thompson replicas...I rebuilt it all to better than new condition (stock and metal finish) and only replaced the barrel and loading magazine tube...The inside mechanism was in perfect brand new condition and those are designed to last forever assuming that you lube them right.
These guns were originally designed for shooting #2 lead shot (.15 cal) but many guns were made in .17 and .18 calibers for shooting #B & BB size BB's ...The backstops used at the fairgrounds were designed for not reusing the lead BB's but many fairground stands reused them even though they got deformed and jammed the mechanisms often...I re-barreled this gun with a .177 steel smooth bore barrel for shooting regular Daisy & Crosman steel BB's that are found anywhere and improved the system by magnetizing the loading breech mechanism (picks the BB from the magazine and brings it up to the barrel) so if you stop shooting and point the gun downwards there is no BB dropping as it happens with all of the lead original barrels...
I re-sized the Red Star targets proportionally to the new .177 BB size and print them at home in target paper...As it is, the gun is way more accurate than it ever was shooting lead and if you do your job, one hole groups at 8-10 meters are very easy to shoot...I use a 4 x 4 ff. frame with a Kevlar backstop and extra heavy canvas for the sidewalls for those sporadic ricochets, the Kevlar mat was my archery backstop and at the bottom of the frame I have a strainer for separating paper coming from the targets from the BB's attached to a cloth funnel connected to a 5 gallon container for recuperating and reusing the BB's...
The setup works amazingly well and all it takes is 100-150 PSI of air pressure and either an auto oiler or a drop of pneumatic tools oil every now and then...I cut the tubes for loading he magazine to hold exactly 100 BB's as intended in the original game and it only takes 5-10 seconds to load the 100 BB's into the gun's magazine (hole on the butt stock)...I have 100+ loading tubes and those you load by placing them all together inside the BB's container and dropping the BB's from above with your hands (It takes less than 1 minute to load those 100 tubes)...
Shooting the RED STAR is very and I mean VERY addictive and the good thing is that it doesn't cost anything but paper, a little oil and compressed air!
