Thanks @62caddy - One would think there would be a Registry of sorts for these. Maybe I'm just reading too much into it.
@c_dk I am not looking for name and addresses of owners - just a simple build date / sell date, if the unit was ever in for service. Registries exist for exotic sports cars, boats, vintage planes, etc. so I think it is a safe idea. All I want is an approximate build date range of my C40 and if it has been returned for service.
Yeah, what you are looking for is totally reasonable. I think c_dk either misunderstood or went off the deep end.
As a manufacturing company McIntosh's allegiance was to their dealers and to the orginal owners not collectors decades later.
Deep end, I was trying to be diplomatic......they truly have more important things to do.......
