My Ospreys have the parallell tap, shared with the Trackers.
I read elswhere that Ospreys have tapered taps, this leads me to think there are two generations of the model?
Also, thanks for the info on the internals, and the tap-shimming.
If I find differences between the Tracker and Osprey transfer ports, I will post them here.
I've sussed it Alistair
Early Osprey taps were tapered and Osprey MK2 taps were parallel as shown by tap part numbers here :-

I think it was a Tracker that Jim played with that Edbear made a new shim for.

The Osprey was a complete goat compared to the Hammerli 400 series.
No need to be rude I know but it was.
Baaaaaah!
I'm happy for you to call Webley all you like Alistair --- they turned me down for an apprenticeship.
Mind you, so did BSA.
All the best Mick
Interestingly Alistair
At the time (1977) BSA said they weren't gunsmiths as such but a precision engineering company.
Webley did send me a nice book on Webley history along with my dear John letter, so it wasn't all for nothing.
All the best Mick
