Thank you for coming back on my dismiss of the 760. We are very close I guess. The first picture I saw of the 760 was so bad I could not see the hinges and the drawing was so diffrerent. With this PDF , and after cleaning one I can compare more details. It is an Altman for sure but a later...
The gromets where made by HEYCO but there is no reference on their site for the 5K-1 code.
It may be a retrofit but there is no traces of previous device.
The bulb is a 1K on 120v.
Many thanks.
I need help to identify this one.It's not a Kliegl 1143 or 3440 nor a Strand Patt 750 neither an altman 660.It has a 1K mogul screw bulb , I think it could support a 2k
