No. A 149 in Bordeaux with a gold-plated cap never existed; offers of the kind almost always rest on a confusion with the 146 or the 144, which were sold in Bordeaux and in doué versions with a metal cap.
Of the 149 itself, collectors report only two Solitaire variants in the regular range: Solid Gold and Solid Platinum, that is, the versions made wholly of precious metal. Otherwise the large piston filler is listed in black precious resin with gold-plated fittings. If a 149 is offered in a different colour or with an unusual cap, particular caution is called for.
