WTB TM / Cybergun / CYMA spare magazines! M1A1 Thompson

I'm looking for Tokyo Marui or Cybergun / Cyma spare magazines.

they must be of metal construction. Must be the low cap or mid cap versions. ( I do not want the wind up on the bottom of the magazine, I want the simple spring loaded version, low cap preferred!)

Depending on price I'm interested in up to 4 of them.


Thank you kindly!
