The Siren Board

I just did a search for R. J. Zievers Inc. on Google, and, this came up:

https://books.google.com/books?id=Ak7RX ... c.&f=false

Section 5 deals with warning devices. Sorry if this has been mentioned here before. Section 5-B has a number of siren makers.

Wow...thanks for sharing this! I never heard of R.J. Zievers, Inc before...anyone have and info on that? I also find it interesting how Sterling's listings mirror Federal's in both B and C class...
