Title: Pittsburgh Transformer Company
Post by: Nevada Willis on January 25, 2017, 01:50:51 pm
Hey gang.

Does anyone have any info on the Pittsburgh Transformer Company?  I fell into an ancient bowl reflector lamp with a cast ribbed head.  The reflector has a cobalt blue enamel top.  A number cast on the body is "442."  I'm thinking that it could be a PTC fixture.

Thanks!

It is a Pittsburgh Transformer Company fixture.  It turns out that PTC had a very unique proprietary series street light system in the early 1920s where current regulation took place inside the various lamp fixtures.

Here's an information sheet I put together.
