Did Trippe ever put the larger magnets on their MR-3s, Dan?Referring to the 2 above posts, Trippe Lite's MR-3 had / has it's own unique teardrop shape, as do the cheap China teardrops seen on ebay..
I've had a couple of MR-3s over the years, but I guess I didn't notice that the bases were plastic. Both had the older style magnets like you mention above. I only ran them dashmounted, so I didn't have to worry about them flying off. I've mentioned on another thread about the Junior Beacon that Ellis Funeral Home here ran on their '58 Chrysler station wagon ambulance. It had the old style magnets along with the eyelet to attach to a large sheet metal screw mounted into the roof. Despite the use of the eyelet, that light went sailing more than once, and had to be sent to Federal for repairs. The Chrysler was retired in 1960 and replaced by a '61 Chevy Panel truck that became first out ambulance. Their '59 Ford wagon which had been first out became backup. The Ford's red 17 beacon went on the panel and the Junior from the Chrysler went on the Ford. But this time the Junior was permanently mounted on the Ford, eliminating the previous aerobatics of the Junior.On their original MR-3 they used 3 magnets similar to, but larger than the ones Federal used.
They still produce a MR-3, not sure of the options on the newer one, although the base is plastic, so I doubt it..
Thanks, Dan. That's what I thought!Skip, the new MR-3 bases are plastic. The older ones were aluminum.
Did this one seen any actual use, Dan? Looks like it's hardly been out of the box.I have others in this condition, (duplicates), but I can't seem to pass these up when they come around. The original owner has kept it protected from damage for the over 55 years that he has owned it. It is in NEW condition. That would make this an early version FB-1, 1960 or earlier.
OK, here's another special Fire Ball to add to my historical Fire Ball collection!
The previously posted S/N 2A10 seems to be the oldest Fire Ball seen so far with numerous design/engineering changes, noted in past posts, not made until the common production run of S/N 2A12. These things that would be eventually changed include, safety mounting eyelet on the bottom of the base, screwed dome retainer clamp replacing steel swivel clip, older design reflector, and vibration plate under the rotating mechanics.
This one has a S/N 2B10, and has only the newer dome retaining band screw clamp, and not the other coming changes. This also has the old style metal cigarette lighter plug common on the older Whelen ROTA-BEAMs.
.....as far as I can see.....until I receive and refurb the light....... 2A10-2B10-2A12?
More pics later

Whelen used these plugs, but the switch would have been added by the user.
Federal Signal's 2nd Version Flash Ball was still a non rotating light like the Version 1, with some design changes.
It had the larger magnet, was available in halogen or incandescent bulb, and had a new reflector and socket design.
The reflector was still stationary. The bulb was flashed by a flasher for a directional warning.
These Flash Balls are even more rare than the Version 1 Flash Balls.
