Gentlemen - I will try to start some sort of accounting for the Thompson Center Lucite Blocks. Perhaps someone who started saving gun catalogs before I did can fill in.
My earliest catalog is c. 1984. It is Catalog Number 12. this is the only catalog I have that shows the Lucite Block with only the representation of the Thompson Contender Pistol in it, which was T.C. Product Number 9603 and sold for $15.00 in that catalog. It does not appear in my catalog 20 (1993 or any catalog thereafter)
Also in that catalog is a round Lucite Cartridge Display, unnumbered both on the display and in the catalog, Product Number 9600, which sold for $55.00. The one pictured is round, and has 20 cartridges on it. I cannot read the captions identifying these cartridges.
IHMSA80x80 shows a block that he has identified as being from 1985, which is also round but only has 17 cartridges on it.
My next catalog is Number 20, from 1993. Both it and Catalog Number 21 from 1994 show an Octagonal Wheel #6, Product code 9602, $95.00, which has 19 cartridges on it. The wheel appears to be numbered right below the TC Trademark in the center of the display. That would square with my own Display #5, which is also octagonal, and appears to be indentical to Display #6. I assume there is some difference, but mine also has 19 cartridges on it and they appear to be the same. Unfortunately, the pictures are small and I can’t tell
From Catalog 21 thru 29, 1995 thru 2002, an octagonal lucite cartridge display #7 is shown, It has 18 cartridges on it and is marked with the Issue Number. Product code was 9602, the same as for Wheel #6. It sold in the 1995 catalog for $95.00 but by 2002 in catalog number 29, it was $105.10, not really a terrible price increase over a seven year span. By that catalog, the product code number had changed to 9607 (catalog 24, 1997. is the last to show the product code of 9602, with catalog number 25 of 1998 beginning the new product code of 9607 for the same product).
The lucite displays are dropped from the catalog number 30, 2003, and do not appear again.
That is the best I can do between my own, single display #5, and the catalogs I have. It is not complete, but we do what we can with what we have. If anyone has any duplicate TC catalogs before Number 12, and from 13 to 19, or the catalog number 34 (?) for 2007) to give away, I sure would like to get them. They help me to help others. Missing the SHOT Show in 2007 was a disaster for my catalog file - I have only 5 or 6 catalogs from all firms for that year, instead of the more than 100 I usually bring from the SHOT Show. I will be going there this year!
