Yes-those KGM displays are really quite interesting.
Has anyone come up with an LED replacement for the bulbs in them?

I've seen edgelit displays in General Radio Equipment with digits 1 thru
0. The displays were made id England by KGM Electronics in the 60's I
think and I believe they used type 327 or 330 bulbs. I sold a
Synchronometer using these displays on ebay back in April and it can be
seen here: <

The displays were really interesting and they worked really well. With
so many bulbs though, they constantly had to be replaced.

I found some displays in my boxes.
They came with original box but no datasheet.
I can light it by 5V,and I think 6.3V is better.
So,Has anyone seen this display before?
I had a voltmeter with those displays. Hang on to 'em, they're really
nice (or you can sell 'em for a fair bit).
if you have,and you can trade with me,please let me know.
Or,I have to copy one in the future.
I've seen people make their own edge-lit displays like this using
laser cutters or CNC mills to cut the digits
into clear plastic. You can light the layers with incandescent bulbs
or LEDs.
