How come everyone always forgets about the roulettes and NCVs?

If you are one of the lucky people to have a complete CHIP collection from the Hard Rock then you have to include these. Even the Pindex and Pink Taco type chips have to be included. Maybe not as far as house chips on those but the roulettes are a must. They are used in everday play.

I have complete sets of the current Hard Rock NCVs.
I also have the complete roulette addition from all 5 tables and the issue before that with the BLACK Hard Rock lettering round the rim from all 5 tables.
As far as know there were 5 tables with a different color flame for each.

Can someone answer these questions for me?

Where there two issues for the NCVs?

I have heard the current roulette issue in use at the HR is to be replaced soon?

The roulettes with numbers 1 and 2 on them refer to a set from each of the original 2 tables they had, correct?

There were no flame designations for tables at the time?

How long were the #1 and #2 roulettes in play?

Are there any know variants to these sets as far as inlay size, font type, etc that anyone has found?

Sorry I wrote a book. Very curious.

Thanks.
