Webley Osprey questions please.

[Geoff555]

Many thanks to you all. Blimey Rovercoupe mine is brand new compared to yours, best wishes for that one. Have cleaned off as much rust and things as I can. Cold blue arrived this morning so will have a go at that. Will be satisfied to save it for the future, I don't know how popular they were but I really hate to see things scrapped.
Thanks again it will take some time but I will let you know how it goes.

You have to reblue the side lever or it will look odd, polishing is the important part using finer grades of wet and dry to p1200 or p1400; good degrease with meths latex gloves will prevent finger marks and stop your fingers going orange!

Its on the list to do the sidelever but it depends hot my experiments in hot bluing go, if it goes well then I will do the whole gun again.

I did the cold blue a bit different this time where i applied the blue and then kept it wet with water for 5 mins at a time to let it really go and it gave it a nice deep finish somewhere between the blue and black finish.

The weld fix was comedy though and had to be sorted without warping the cylinder.

The rear piston skirt always gets quite scored in the Osprey, it might be from travelling over the anti-beartrap slot. I've never found it to matter, if it bothers you just wet and dry it and polish it back to shiny.
In my experience, PTFE washers don't work well in the Osprey, probably because of the large transfer port. No significant increase in power, but piston slam and dieselling become the norm. If you're going to machine the front of the piston, which you would have to do when fitting a PTFE adapter, then fit a leather washer. This will transform it into a sweet shooter that will do nine foot pounds all day long on a standard spring. Forget uprated springs - they will make it shoot horribly. and the back block crosspin holes will be oval before you know it.

Hello that is useful to know about the piston rear skirt, it is heavily scored but also worn, so much so that the raised portion of the skirt is no longer raised and going into the piston! I do have some leather piston seals from Gem and BSA underlevers, will have a think about that.
Thank you.
Cheers.
Geoff.

As mentioned earlier, the Osprey has a rather large transfer port for the seal type. Seems like Webley learned something with the Osprey, the Trackers have a smaller port.

If you dont go the suggested route of conversion to leather seal, it is probably a good idea to sleeve the port.

My "tinkering" Osprey has its transfer port sleeved down, and the piston converted to take a 25mm HW seal. This made the firing more pleasant, and increased energy/velocity.

Here's my Osprey and Ospracker (Barrel snapped so I replaced with a Tracker barrel!!), Both are a bit 'slammy' to shoot, Converting to a leather piston seal sounds like the way to go!!



Some sidelever bits, The cammo Tracker has gone back to it's original owner (He had it from new!)..




And the snapped off barrel stub after using an easy out to remove it!!
