Some FoMoCo parts have original parts markings, but some do not. I've never seen any FoMoCo ID markings on this particular 'Bird part.
Related to Kultulz's inquiry, I've seen several '55-'57 'Bird timing chain cover front engine mounts that have been scored by the 'Bird's crankshaft vibration damper 'donut' moving so far back as to permit contact with it when the engine is running. This 'donut' contact can emit a high pitched, intermittent chirping noise when the engine is idling in the early stages of the 'donut' having moved out of place on the damper body. Paul's support mount is in pristine, unmarked by the 'donut', condition!
I hope this helps someone!
