[vcf-midatlantic] Somewhat OT: Friden STW-10?

[Jameel Akari]

Friends and coworkers have been asking me about VCF-E.  In conversation, a 
friend reminded me of a somewhat related machine:  he has a Friden STW-10 
mechanical calculator that needs some sort of repair/service. 
(Carriage/accumulator doesn't shift correctly)

Anyone familiar with these?  You can contact me off-list.

Thanks,
