Possibly a rear rack I know I've seen it in an old vintage bicycle book somewhere, I will update the listing if I find it.
Approximately 5" 3/8' (13.5mm) at fixing point
Nice solid and strong rack still fit for purpose!
Probably requires a respray but I'll leave that up to the winning bidder and leave it untouched.
Farm fresh for now! And yes it did come from a farm, I can't say it's been there all these years but it's a true farm find for me.
Happy bidding
