Re: Re: Essco Phila ?
I think it’s like the second bell I mentoned.
I’ll bet your ESSCO PHILA is really the E.S.S. COmpany (ESS Co), Philadelphia (Phila)
Probably http:\www.esscosafety.com is the company in question (they abbreviate their name as ESS Co) and the bell is likely a part of some sort of warning system, such as a clanger for the train track, or exiting vehicle warning or some such.
I’d try writing them with a photo and see what they say!
