A New Member of the Family
You would not want to read a great many paragraphs in this type, but for technical drawings it would make very good labels. This is a Tower Constellation, a wide-carriage portable typewriter made by Smith-Corona and sold by Sears for about three years in the early 1960s. That alone makes it a rare beast. Five type styles were advertised as available for this model, and this was not one of them. It looks like Smith-Corona Elite Gothic no. 16, and it must have been a special order.
This is why it is worth moving aside the debris in the junk shop: because there may be something you need at the bottom of the pile. You may not have known that you needed a typewriter capable of labeling a tabloid-size technical drawing, but once you see it you realize you cannot do without it.
