Hi Esteemed Group ~ Does there exist any documentation that could shed light on when two features were added to the DD machines? A young friend (actually my RCATheremin.com co-creator Mike Buffington), today acquired his first antique phonograph -- The popular Edison Diamond Disc BC-34. He's always interested in the historical details and would enjoy knowing when this machine was made, or nearly when.
The features I'm wondering about, that this example has, are: a) 10 & 12 inch tone arm stop buttons (as in the Edison Long-play machines); b) The shock-proof governor assembly. The serial number is 45005 and I think I read in Frow that the BC-34 production run reached around 52,000 units and production was concluded in August 1927. I guess this makes it a late '26 or early '27 machine? Anyone know when the above mentioned features were introduced? Best to all, Andrew Baron Santa Fe _______________________________________________ Phono-L mailing list http://phono-l.org
