Bren MKII rescue~

[Flying10uk]

Did you use the same jig on this MK2 as you used when you welded the MK1 or are there differences in the receivers, between marks, that prevent the use of the same jig?

I'm thinking that, theoretically, the same jig should be able to be used on the MK1 and MK2 Bren because the upper and lower receivers are interchangeable but what works "theoretically" doesn't always work in practice.
