It is funny how manufacturers rebrand products and form partnerships that help expand product lines. Smith-Corona was the master at rebranding its products to sell, sell sell!
This is a good example; look at the two typewriters featured here as both are Smith-Corona machines.
The nice yellow Tower “President” was sold by Sears, yet is really just a spiffy Smith-Corona Silent like its cousin in gray.
Both machines came into the shop the same day for service. The Sears needed general cleaning and oiling plus a type bar was not resting back on the type bar rest. It took a few moments and I found it; under the machine is another rest with a cork pad. The pad had shifted causing that one key to stick up. Oh, and some time long ago, someone used spray lube on the segment and carriage (heavy sigh). I have my own “spray lube” that I mix myself and it worked quickly to clean up the old stuff.
The Smith-Corona needed heavy cleaning with many type bars sticking. It also had several bent links that were causing the machine to misbehave. The platen had three raised spots that turned out to be some black goo that needed scraping off, weird.
The funny thing about these two machines; they both type EXACTLY the same! Really good typewriters.
