Webley Service Mk2 part required.

If you need to get one made, copies of the original drawings are on my sig site. Just go to the 'Webley Service Air Rifle' section and look for the 'Service Sight Drawings' sub album which is the third to the right.

Like gold dust. its a left hand thread.web, mk 3 sights complete should fit im told.

I enquired at knibbs and they may produce some soon.

As stated above, a Mk.III dovetail fitting rear sight should fit, if you can find one.

Isn't that screw a left hand thread

Looked at mine today. Seems to 5/32 or possibly 4BA couldn't match the pitch.
Irritatingly it's very close to M4 which I have in Left Hand tap & die.
Which bit do you have?

[mark@mbb]

I have the rifle with the round nut on if any one local can copy it

[Troubledshooter]

Presumably this is the adjuster you require:

which does indeed have a Left Hand Thread as marked on the drawing.

It will be easier to read if the 'full size' at the lower left is clicked.
