That appear to be a top quality font and I'm sure the winning bidder will be stoked.
Lock-in adapters aren't "old", they are still used in pubs today. Many publicans prefer them because they have two o'rings (better seal) and it's harder for punters to steal the taps. Furthermore, these lock-in adapters appear to be stainless steel and therefore top quality.
I doesn't appear to "need some fixing", it just doesn't have the bottom nut used in to seal the font in the picture. mr_tyreman is this available?
If mr_tyreman doesn't have taps to go with the font, I can offer the winning bidder a variety of lock-in taps.
