My most recent 127 was around 200 or a bit less at auction. V good stock, sorted trigger, some thinning of barrel bluing, though not too much, no iron sights (but I have some in the spares box) and a mediocre scope in mediocre mounts which has been replaced. 124s maybe command a 10-20% premium. Maybe.

You used to be able to pick them up for comparative peanuts. These days, you will see the guys on g* asking stupid money. But I agree with landymick on the broad price range if you take your time.

Personally, even in excellent condition, I think £250 is still a lot for a classic springer, and £300 is a very big deal. That gets you into or above the territory of almost any used HW, most used AAs, Webley Tommies and Bows and Omegas, Superstars, etc. And "new old stock" HWs, AAs, "Walthers" at auction.

So, as a Sport owner, I would love to encourage people to think that my FWBs are now worth £400-450. But they aren't. Unless they are as new in box with all the bits, or period customs.
