Have a Grizzly KA-03971. Can't find a site with info. or looking in the wrong place. Thanks for any ideas

Try Looking in the trad History and collecting forum a few notches down from the Pow wow option.

Good Luck.

Does it look like 150603866848 on the auction?

Close but mine has a radiased shelf.

If the color scheme is the same as the one mentioned above it's somewhere between 1973 and 1976.  I read some theories on how to date specifically within that date range but I don't recall where I read that information - TG or some other source.  

Have seen several folks speak highly of how that era shoots.  Have not had the opportunity to hold one yet myself.

Thanks for the info.
Mike

Is yours 58" or 56"?

It's 58"

I've had a few Grizzlies with a KR but never one with a KA serial number. Is it a Grayling bow?

I'm with Jack, don't know about a KA. Post a picture if you can.
