A while back I found a spare No1Mk3 Magazine cutoff and screw. I had bought it years ago and tossed it in the parts bin. When I found it again, I listed it on ebay. Then I got a message asking me if the hole had been welded over.....

I hadn't even looked it over when I bought it or when I listed it. A buyer pointed out that it was not a No1Mk3, but a No1MkV cutoff. It sold for well over $100. The wife asked if I had another one and I laughed and told her I'd probably never see another one. I only ever bought 2 spares anyways.

This week I found the other spare I bought years ago........Yep, No hole, another No1MkV and it's already at $43 on ebay.

I wonder how I would have done over the last ten years had I known the difference?!
