hi all, i have been asked to value/sell some brakes from a work colleague, im not asking for values here (xyz will be getting that one) just a model and year and maybe a rarity value. he said he bought them new but cant remember if it was 70's or 80's and he has no interest in cycling whatsoever. he also states they have never been fitted to a bike and have only spent the last 30 odd years sat in an ice cream tub in his shed. the marks you see in the pics are mainly dirt and there is slight pitting on top of the barrel adjusters and main bolt other than that the are as new as well new ones i guess.
