Selling old fire alarms

I’ve got a bunch of 4251-20s and 4051s with plates and a couple projectors. What would be good prices to sell them for a piece?

50 to 60$ Would be a fair price

Based on previous EBay listings I’ve encountered, here are my suggestions.

4251-20s: $30.00 - $40.00
(based on condition)

4051s: $45.00 - $65.00
(If you plan on selling the plates and projectors with the horns, I’d go higher than $50.00.)

Otherwise, I’d list them for how much you paid for them.

I took them out of my school when they changed them

Are they going on eBay

When I figure out how to do eBay then absolutely

Ok . I will look forward to seeing those alarms on eBay

you can always donate some to a fire museum(s)

The projector is actually called a Simplex 2905-9907

I used to go to a Catholic high school that had these exact devices but the signaling devices were semi-flush mount 4050s.

5001/2 if you’re talking about the ones from the 60s and 70s. The OEM was faraday, and sold to numerous companies, which re-label them as their own.
