Yes Barry.
Chambers only have one part number for Weihrauch break barrel rifle breach seals --- BS040.
One seal fits all.
I haven't changed my breech seal on my 80 since the new barrels have been out and they look to protrude a little more
(perhaps I am wrong) Also what is now considered the best breech for the 80, I still have the old white one

The Aussie Custom Seals ones are far superior, I use them in old and new models.
Some of chambers .25 break barrels use OR097 and not the standard BS040. Hth.
