Headlights for Diamond T

[Slava]

Mack's (NR's at least) had two kinds of mounting. With a ball and with a cup. Can't say yet what one was early and what was late.
Remember only I have brackets of the one and lights of the other (I'm in a sorrow of they are rotted through).
Headlight bodies have brand mark stamped on a top, need to look in the shed.
