Anyone familiar?

From the Alvarez site.

By reading the number stamped on the heel block of your Yairi, you can tell in which year it was made. The first two numbers correspond to the year of the Emperor of Japan at that time. (See chart below.) The second two numbers refer to the month of production.

Thanks but I don't have that kind of bridge.

I don't think you need that type of bridge. The numbers down below apply to Alvarez guitars dating back to the early 70s. I know that bridge wasn't around back then.
