50-100 USD Another Answer: Depending on the condition I've seen them sell for over $3000
The Webley Scott Mark 1 was made from 1924 to 1935. It was made in several variations. The first two variations are so rare that a price can not be established. However the third variation in very good condition is worth around $325. However yours may be worth much more. My best Guess is $475 + , But That is only my opinion.
Somewhere between $150 and $200
Obviously depends on condition. £45 upwards. Does yours have both .32 and .22 magazines. I am an athletics starter and need a Mk2 to start school/children's events.
More information would be helpful -ie, revolver, automatic or flare pistol, and what bore ?
The easiest place would be amazon or a online air gun shop. ---------------- New Answer ------------------- The Webley Mark III is a rifle not a gun and has not been in production since 1975. You could try a gun shop or online Firearms dealer. Several firearm dealers sell used air guns & rifles.
