6635 steel Rolex bracelet

Hi to all...this is my 6635 Rolex band..as you can see it has the 57 end links with 13 links not including end links..its stamped 2 67 for early 1967 and is perfectly stiff..no sagging on the links, if came on a 1967 Tudor Oyster Royal which I believe wasn't standard on thaf watch..I'm thinking its a Gay Freres , although not stamped.Can someone give me a true and fair valuation of the bracelet please..it does have some small scratches but mint otherwise..many thanks.

Always difficult to value exactly, but no more than a couple/few hundred £/€/$
