---------------------- multipart/alternative attachment Dan and list: Until recently I thought that the SF10 had accu-just hitch pins and the suspended plate system, while the F had the traditional hitchpin arrangement. However, in the past year I have seen an SF which had the older style hitchpin setup. The serial number dated it to 1969. Apparently, there was a time when the SF scale was still made with the old plate system. For some reason I see quite a few SF's around town, but few F's. My kids' piano teacher has an F, but that's the only one that comes to mind. I think that it does have tunable duplexes. Yes, it is a nice piano.
