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.
All the best Mick
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
BSA must have based that idea on their history of making precisely-engineered motorcycles (hahahahahahahahaha!) as my 1973 Meteor has numerous deviations from the concept of 'precision'. I see no-one is clamouring to buy the 'piled arms' badge to stick on a Shanghaicycle.
And Webley sent you a history? Well, they are now. Innit.
Tant pis.
