Webley Service MkII - replacing the breech seal?

[Mr. Gain]

I have acquired a Webley Service MkII in .22 that is in generally good order.

However, the barrel lock-up is quite loose and the bolt applies barely any tension on closing.

The current seal is completely flush with the receiver.

Would I be right in thinking that a new seal would sit somewhat proud of the receiver and thus take up the slack?

If so, is there anything one should know before buying/fitting a replacement?

I tried using these ones from Knibbs but they kept disintegrating,

so I ended up using a yellow P.U one from T.R Robb which works very well although it’s a shame it is bright yellow. I wanted it to be a good shooter.

Thanks, Matt, that's really useful to know.

Do the Knibbs or T.R. Robb seals sit proud and give the bolt/barrel some tension on closing?

Yes, the bolt handle closes tight, nearly touching the cylinder.

Sounds good. Thanks

Is there any special knack to removing/inserting the seals?

Edit: I've just spotted there's a recent WS Mk2 breech seal thread on here: http://www.airgunbbs.com/showthread....ce-breech-seal

Alternatively and assuming you can remove the old one intact, consider adding a shim behind it.

Not really, just used a dental pick to get the old one out and then pushed the new one in and clamped the barrel bolt down tight.
