Raven EU18 Series Spare Part

[Sampson]

Hello chaps,

 

Purchased a Raven EU18 Series pistol and the magazine that came with it was leaking, naturally I decided to take it apart to try and fix the leak, completely forgetting about the spring which pinged out. 
 

Long story short, I lost the baseplate latch that goes at the bottom of the spring and I cannot for the life of me find a replacement anywhere for sale. Does anyone know of a seller that has the following? 
 

Part 74
 

Thanks in advance
