Rolex 6635 Steel Bracelet Valuation, 1967 Dated

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 £/€/$
