There’s a FWB Sport 124 listed in that auction. It’s described as being engraved by Don - but it most certainly isn’t (have a look at the cuts - my dog could chew neater).
Don told me about someone who used to knock out work using a Dremel and pass it off as his stuff, this looks to be one of those.
Just didn’t want anyone bidding silly money on it only to be extremely disappointed.
