As far as I can tell, one of these is not listed in TCR.

I am assuming that

Chip on LEFT is what TCR describes as "Lt Green/Red" dovetail.
Chip on RIGHT is what TCR describes as "Dk Green/Red" dovetail. (Interestingly enough, the same colored Fort Lucinda dovetail is described as Purple/Green.)

I believe that the middle chip is unlisted. Scan color did not come out well. Should have been what I would describe as a "gray with very light green hue". Bought it from Jerry Wall many many years ago. Recall he had both the "lt green" and "gray" colored versions. The "gray" colored chip came only with a gray tail. No red tail versions.

1) Does anyone have the chip shown in the middle?

2) Does anyone have an UNDRILLED version of the chip shown on the right?

3) Is the chip in the middle an unlisted chip in TCR?
