there are 2 variants of that type shape bottle, the one you have and the one more popular is with the filler hole in the middle, i cant remember the part no off my head but its embossed in the front
however, someone already makes a repro of the one with the centre filler hole, and it usually retails around £55, but it has the repro company logo and not the ford part no on the front
now if you could copy that bottle, complete with the ford number, at a reasonable price, rather than a repro name or nothing at all, ie it looks like a genuine one, then i think you would have a market, genuine ford NOS usually fetch anything between £200 to £250 a pop, theres probably a market for the one in your picture, but it would be a lot smaller, i have seen very good used ones go over £200,
the original bottles suffer with going off colour, but they also split on their mount slides, small splits can be repaired, but wide ones deem the bottle scrap
