6/13/19 - This is an original WW2 era production Thompson SMG magazine. The magazine holds 50 rounds and is fully functional, so please do not purchase if this is not legal in your state. The magazine is in great overall condition but there is some minor rust on the sides and near the loading mouth. The bluing is in tact and excellent throughout the magazine. Strong spring but we recommend not winding. the magazine is marked "Type L" for the 1928 model. These magazine are very hard to find all original and in this condition.
