Engineer Don McCourtney started this company in or before 1961 at 3389-91 Brownlow Ave.   They were “custom molders of thermo plastics and thermo set for the industry, miniature and sub-miniature plastic parts of close tolerance.”  McCourtney Plastics was what is known as a job shop. They did not make anything specifically for themselves but tooled up and made other companies’ products.

In 1964 McCourtney built a new factory at 7309 W. 27th Street (a/k/a 2700 Louisiana Ave.)  Here is a sketch of the new building:

Don’s son Patrick died the year before Don sold the business, which he had been running with his other son Jerry.  Jerry continued with the company for a few years after the sale under an employment contract.  McCourtney is still listed at the 27th Street address.
