Grinnell Bros

[L. Verkoelen]

Hi List;

I serviced a Grinnell Bros console today. The customer is looking to buy a
new piano and wishes to sell this one. I was trying to look up the date but
havn't had any luck. The S/N: is 400762
There is also a "200" imprinted over the S/N. The Pierce atlas doesn't list
anything over 5 digits. It mentions later units made by Samick but these
supposedly had letter designations in the S/N.
The piano is in good condition and my guesstimate places it around 30 years
old?
Does anybody have any info that would pin the age down?

Thanks
