Hi Bill, Those are Manco 5 inch. Ruttman used the Taco Style 5 inch. They are close but only have four ribs in the rim. Those are Manco Snowflake Rims. But see how close the fender bracket is to the tire. No room for a fender. So it was a 4 inch steel rim. I would need a close up of the front corner of the engine plate. And to see if it has original weld on the foot bar. It has the later larger triple trees like late 68' or a 69'. If you do not have a serial # stamped in it it was a kit. I bet if you looked under the paint you might find it. I have only seen three un stamped kit bike survivors so far all these years. Not that it is rare just most were sold thru the dealerships as a running bike.
