Frame # 1017528 engine case # 1017838

I have owned my CB 750 for 47 years. I installed a Weisco big bore kit and Jardine headers in 1981. I painted it with lacquer over 40 years ago and despite the lacquer cracking it still looks pretty good. The frame tag is riveted on. Can someone tell me what I have in regard to collectability? I have the original brown Oklahoma title which is rare in that Oklahoma went to a larger green title over 30 years ago.

Welcome to the forum.  It looks like you have a 1970 CB750 K0 with build date of 12/69.  I think the value would depend on condition, mileage, and how close it is to original.  Having original parts like unstamped 4 into 4 exhaust, wrinkle tank, rolled rear rim, ducktail seat, original paint scheme, double cut fender, 2-hole rear hub, etc add more value.  I have seen prices anywhere form $4,000-$12,000.  Hope this helps.  Post some pictures when you have time.
Cheers
