I am looking for a working unused PHILIPS MBF/U 125W PowerWhite lamp from the 70s with the original packaging.

In exchange I am offering an unused NARVA HQLS 125W lamp (phosphor: orthophosphate) or alternatively NARVA HQLD 125W (phosphor: yttrium vanadate).
Both lamps are with original packaging, working, unused and from the seventies and E27 base.
