LOL! I like his reasoning.... but it's not a 185-15.
It's a very uncommon model 15.

A Singer 15-125. Care and feeding should be the same as the 15-91, if you don't have an original manual.
It's a beautiful specimen!
A clone is by definition -not- a Singer.
How the clones came about (I can't remember where I read this, if someone can point me there again I'd be darn grateful!)
After the second world war, Singer "gave" the design and rights to build the model 15 to the Japanese to help them rebuild their economy. Before long, a flood of Japanese machines (with typical Japanese precision build) were hitting the market, some looking identical to the Singers, some evolving to take on their own shapes and looks.
