About 12 months of research and a lot of work.
This copy is close to the original, inside and out.
A diifficult restoration combining a Polish case, fitting a good copy? lense into it.
The base was altered to fit the case properly, the interior parts all hand made.
The front mounting screw re positioned as original. The case is only in etch primer.
Originally Bosch fitted a 6V 3W Bulb, which I will, otherwise the close position to the lense would cause heat distortion.
As far as the illumination value I would not stake the drivers behind to see it regardless of the brightness
so a hand signal would be best practice!

JN7

Hi -

My info shows that the JN7 originally did not have visible rivets holding the lens into the top cover. I think, if you find a way to close the holes, and retain the lens, you will have it.

Bosch JN7 Rivets

See Bosch diagram, there were 3 rivets holding the lense into the top cover.
The diagram has omitted the top one.
Can we see your reference?

Bosch JN7 Lense rivets

Jeff, you are correct, some had 2 others had 3. Also whats interesting is the base was painted white on this version.
The one I copied appeared black.
