Durham Duplex Handles?

[ShaverAZ]

i read somewhere long ago about Gillette razors being sold with Durham Duplex handles. Supposedly briefly sold in
Canada if I recall correctly. Does anyone have any info about the timeline for this & which Gillette head was used (1930's Tech?).

I'd like to know too, I have one and it's a fantastic handle design.

I always thought that these were Frankenrazors...
