Quoted from xamindar:
That Grand Lizard looks nice.
On inserts, what are the options when they are 40 years old and faded?
My BK has those jeweled inserts that I am pretty sure are unavailable.
Do you just stick colored LEDs under them and call it a day?
Or is there some colored overlay that can be used?
Honestly the options are few. First clean the underside of the insert. I can't tell you how many times I see people complain how 'dim' an incandescent bulb is so they put in LED's to brighten the insert, but the insert itself is completely filthy underneath. Second, you can clear coat the insert to eliminate cracks and fissures that dampen the brightness. Faded inserts, not sure that is fixable, but cooled LEDs could be the answer. I would resource your inserts though, most inserts can be found. In fact, because BK has been done by CPR there could be all of them floating out there. You'll just need to check with all the common sources.
