All About Pocket Knives

Trying to get some info about a Case Classic Bulldog I recently acquired. Here's what I believe I know. Pattern number is 61072. Build date is 1990. These stampings are on the blade.

It looks like a yellow bone with "bomb shield". However I do not see it listed in the price guide. Is the list exhaustive?

Please see attached photo.

From what I see in Steve's book Collecting Case Knives, bone was called a Clasp, stag was the Bulldog, and horn was the Buffalo.

I don't believe there are any Case Classics in Steve's book,has most were made by Queen.
It's hard to say what color they called some of the bone.Many were very close to the same,tan,green,honey,yellow etc.
