This is a 1/6 scale German MP-38 & MP-40 combination machine gun made by Twilight Magic Works, most likely in China. There are 2 upper receivers that can be swapped out to change the model. The only functionality is the bolt is spring loaded & will retract & spring forward, but it does not cock. The trigger is fixed. Complete with the original clear plastic hinged top box with red French fit insert & the paper instructions for changing the recievers. Mint condition. Price: $25.00.
