Hi - the FWB 127 mk1 or mk 3 are more desirable and they have by far the best stocks (i've had more than a few of these myself over the years)
There seems to be more 124's on the go than 127's
As for price - well thats in the eye of the beholder i suppose but if its a minter it would really have to be £200 plus ( but right at the minute everybodys getting ready for xmas so sell now or leave it till probably February onwards )
