Headlight Question

[motor-officer]

Hoping somebody can tell me which manufacturers and what models/years used the following stamped chrome headlight shell:

SEALED BEAM
DIET
No. 809
SAFETY LAMP
Thank you.

Howdy sir,

The one to have on an Indian 341 and 441 sealed beam bucket is not merely the plain one, rather, the one embossed Indian 809 on the top.
