Just got a new acquistion, a Coronamatic Coronet 12? model 6ELW. My wife picked it up for me and this my 1st electric experience other than using a Selectric back in the 70's. It seems robust, she says it is quiet and has a nice touch on the keys. It is missing a small part or two, and I've noticed some substituted screws on the case. I know nothing about these, and I am wondering if it's value makes it worth cleaning and replacing missing parts.
