I am attempting to organize Chris's weight signatures according to when he worked at Orient & Flume (1973-1975), Bridgeton Studios (1976-1978), Lundberg Studios (dates unknown) and Correia (dates unknown). I believe he started his independent career in 1986. I attempted to contact Chris but I believe he is now retired. I would appreciate confirmation of the the dates I think I know and filling in the blanks of the ones I don't.
