Motorcycle Repair: Honda CB450, bill silver, motorera

Question
Hi Bill - I have just acquired an original CB450 Chassis- CB450 3022250 / engine Cb450 3022427 (hard to read). Although a barn find, it appears original and unmolested. Colour gold with white stripe (black pinstripe), long rear guard, drum brake, has flip up fuel cap. I thik it may be a K2 but am looking for confirmation. Thank you for your time...Nev

Could be that there are different color schemes in other markets. The serial numbers indicate K2, but colors seem to be K3 style.
