Where we stil have access to the sticker sheet I believe there was agreement to
use the sticker sheet number with a one-letter suffix for each unique sticker
on the sheet. Hence 168135a et seq submitted to the PT by Imre Papp.
A brief review of a pile of miscellaneous used sticker sheets reveals the
following numbering schemas
no copyright date sheets - 6-digit numbers 168xxx, 197xxx, 821xxx
(C)1993 sheets - 6-digit numbers 168xxx, 169xxx, 822xxx
(C)1994 sheets - 6-digit numbers 169xxx, 170xxx (also 4100330)
(C)1997 sheets - combo 5-digit/7-digit numbers 71xxx/41xxxxx, 72xxx/41xxxxx
(C)1998 as (C)1997
(C)1999 sheets - combo 5-digit/7-digit numbers 72xxx/41xxxxx, 22xxx/41xxxxx
(C)2000 sheets - combo 5-digit/7-digit numbers 72xxx/41xxxxx
Strangley, I have no used sticker sheets from 1995-1996.
So, prior to 1997 there is no conflict with part numbers if we use the 6-digit
number. From 1997 onwards, the similarity of the 71xxx and 41xxxxx numbers to a
few part numbers which we already know is striking.
Existing 71xxx parts seem to be confined to special finishes, such as chrome or
gold.
Existing 41xxxxx numbers seem to refer to the combination of a physical part
plus its colour or applied pattern.
So maybe there is some equivalence between these and stickers just fall in the
same allocation of inventory numbers.
Where we don't have access to the original sticker sheet, Steve Bliss and I
discussed the possibility of using a 3-digit number with a suffix, like
999s0000, 999s0001, etc. http://news.lugnet.com/cad/dev/?n=7693
Although we don't appear to have posted a follow-up to this, I think we
subsequently agreed to use part numbers starting with "s", s1, s2, s3, etc,
which could be replaced with "~Moved to files" if/when we find the real sticker
sheet number.
