Changes to the HW99S piston and TP specs?

[robs5230]

Hi.

Does anyone know whether any changes have been made to piston measurements and TP, on the HW99S from the early rifles to the current ones?

Thanks Rob

Not that I know of, Rob.

If they had I'd have expected Chambers to show two different pistons.

I've posted dims on the other thread.

Thanks Mick. I have no idea how I missed that.

I now know what route I need to chase, with the issue I have, and at least I won't be going down a blind alley now.

No problem, Rob.

I only knew where it was due to my head scratching over the differences between the HW99S and the Oldschool HW50.
It all fell into place when I found out that Weihrauch had totally changed the internal dimensions when changing to the HW99 --- sneaky old Herman.
