Frieden STW

I obtained an old Frieden model STW calculator that was made probably in mid 1950's. It has not been in operation for perhaps 30 years. When I plugged it in aster all this time the only action was some "calculating" noises and little else. Any ideas on where to start to determine how to get this great machine operational again or what could be causing this problem? I used one of these many years ago when I started out in accounting. Thanks for any help??
