Sten magazine parts

[madkiwi]

So I have a Sten mag that I purchased which had no spring in it (but had the base plate and follower).

I can't just buy a spring and throw it in there because they don't come with the little part attached at the lower end that the base plate locks on to.

I found dozens of people offering the base plates but I am finding nobody offering the spring platform (not sure what it is called).

Any ideas? I'm thinking I might have to just take the spring out of one of my Indian 19 rounders as a donor.

It's properly called a "retainer, plate, bottom" in Brit Milspeak or a "magazine bottom plate retainer" for the rest of us. 

The armourer's catalogue number is BE 9989.

I have no idea where to get any but now you know what to call it, better than "the thingy that holds the bottom plate on the mag"

I wish you luck.
