I'm going to guess 75-76 because of the pointy badges and re-enforcement rings. Welcome to the world of collecting. It can be addictive.
That's what is confusing me. The more I read the more confused I get. The serial number is 7 digits starting with 16 which supposedly makes it after 76. It looks to be a 3 ply with rerings, it looks exactly like the cortex wrapped kit inthe 76 catalog, and as someone else pointed out the stands are 76 as well.
