And I think you're right in saying that was perfect --- there's some funny things I've noted on the SCR as well changing from the AA seal to the Weihrauch seal.

I'll post these up when I've calculated them.

Doh... yeah, std size is 3.7 / 3.8mm. Taking it down to 3.4 will be much the same as shortening and keeping at 3.8

How come yours was 3.5 ? That's not a std size, unless the v. early ones were smaller ?
