In addition, after leaving Crosman, Rudy Merz setup a small manufacturing business in his garage to supply precision lead balls for carburetors, so, he knew that business.
Just to add, one story I was told about this precision lead ball business is that Rudy always maintained plenty of stock for each dimension; however, on ordering a two to three week delivery was standard. If customer needed the product earlier, and they often did, there was a premium attached to the order.
Rochester is a very interesting city. It is a city of many small manufacturing businesses often located in basements and garages. These small shops thrived because of Kodak and other major manufacturing businesses in the city.
