Hiya mate & Thanks for the heads up.
I am really replying to the AC GLASHAN AIR MG CORP machine gun trainer ! I have 4 Mk 111 Sportamatic fairground guns,
These are 1950 ish & look mechanically very much like the above?
They are 3/16 th Ball bearing firing Semi-Auto,s
They have I am sure the same " Lift " operated mechanism for loading & Could easily be full auto , What do you think,
I am sure this loading mechanism was used on almost all fairground guns, Simple Very reliable & Will last a million shots,
Ged.
