Hey Murph!

Yes, the image contains my own numbering system...
Also a way of tagging my images... (*vbg*)

The translations are (I think...):

NV010C6 is N3342
NV01155 is N6459

My guess is based on that the first issue would be listed first in The Chip Rack (the TCR Numbering system first appeared in TCR #3 - yes, I do have all eight issues of TCR ...!!!...), and the Bi-Metal (Tri-Metal?) would be listed in subsequent issues of TCR...

Just a curiosity note: The second PMSC listing for the $1 Silver Smith first appeared in the TCR in issue #4...

Any help from the authors of this Great publication would be greatly appreciated!!!

I hope this helps,

Regards,

Dick
