My Merlux (Merkur head, Polish-made Lux stainless handle)
Probak head, Gillette handle.
Did you match that one up yourself or did you find it that way? That could conceivably have been how it came originally if it postdates the Gillette/Auto-Strop merger.
Got it that way off of EBay - my guess it that it was originally sold that way - but I can't say for sure. Even so - it's a Frank.
