Rotators: Grote, Unity, Federal Signal

[bigcat]

I found these on craigslist and picked them up today. I'm not very knowledgable on old style rotators so I'm hoping that people here can give me information on what they know.


They're all in good condition. All the bulbs work and the insides are clean. They all rotate and are very quiet.


First is a Federal Signal P.A. Light Model CJ184 Series A1. This is the light that caught my eye in the ad. All clear bulbs and one is fluted which I know is wrong. Can someone tell me what bulbs should be in this light? It also has a siren speaker in the bottom. Anyone know how to disassemble this light to get to it?











Next is a Unity RV-26. The red dome was initially on the P.A. light, but when I got home I noticed it was a dome on top of a dome and it said Unity on it. Luckly I'd grabbed this rotator too.











Last are the Grotes. One is a 7620 and one is a 7622. They were interesting because they were mounted on a custom bar with two signal stat lights mounted in between them. Home-jobber all the way but it's kinda cool. I'll need one gasket and two domes for these as one was missing and the other is cracked.

If anyone knows the age ranges on these and approximate worth I'd be interested in that too. I don't think I'll be selling them but I'd be nice to know.


If you have parts for these lights, let me know because I'd like to make them complete again.


Also if you have tips/tricks to cleaning chrome and metal let me know.

I'm noticing that you have Unity RV-46 guts & rotator mounted inside of an RV-26 base. RV-26 is two beams, the RV-46 is four beams. That's easy to do since both their bases are identical, except for the model number stamped on the exterior.

The CJ-184 should have 4416 lamps.

Looks like you have yourself a MSP beacon there

Grote domes are readily available at any good auto parts store that sells, or can order, Grote products. (as most around here do)


They should cost around $30.00 each for new domes

About polishing, try this thread:

For aluminum, I use Mother's Mag and Aluminum polish.


Works pretty well.

To disasemble the 184, remove the dome, remove the belt from the small motor pully, take out the three screws from the top. Snap the retainers off of the bulbs, take the bulbs out, loosen the screws behind the bulbs, take the bulb holder off of the shaft, disconnect the connector from the copper brush contact pad, and slip the chrome shroud off of thelight to get to the motor, and speaker.
