Hi, I'm new around here, hello all!

Been looking for an old springer myself to do up over the winter, and Meteor's seem plentiful and affordable.
I've been put off by the slack jaw syndrome myself - I had one in my Youth, and that one used to get loose around the jaws too.

However, perhaps it is possible. Maybe even neatly -

e.g. - heres a pic of a (John Bowkett) fettled breech bolt, nicely done but it looks like an early model.

Maybe the earlier models were not folded steel / hollow ?

Didn't Mercury's have a similar (but not so pronounced) susceptibility with the simple breech pin - up until .. (Mk 3? Mk 4?) ?
