    I obtained an old Bird 43, Serial No. 99099 for about 20USD. I cleaned it up as it looked like it had been dragged down the road. Note the older style slug clamps on the sides and nameplate.

    Any idea how old this meter may be?

    Mid-70s, probably.

    My oldest '43 is early 60s and has a serial number in the 21000 range.

    The "newer" ones have the black knobs. First one I've seen like this.

    I agree as I used this series when I was doing communications work in St. louis during the 70's.

    My newest one is a 738xx serial number, purchased from Navidyne when they went out of business in the 1980s. It also has the same clamps, as has every Bird 43 I have ever seen.

    This one has the Black not Blue Bird logo
    It says Cleveland OH but it also says Solon?
    I always thought this was my oldest Bird.
    Maybe we can all learn something.
    I'm sure there's some Bird collectors on here

    I've got one of those, but it was built by Struthers under contract to Uncle Sam. Uncle used to not like single-source contracts so they would do stuff like send the drawings, schematics, etc to other companies to share the wealth.

    Only difference I can see is the color: mine is beige, not the bluish-grey of the Collins unit. And of course the data plate indicating manufacturer info.

    Bird's patent ran out a very long time ago and their entire circuit and theory of operation is on

    Several companies manufactured basically the same thing, and the elements are interchangeable.

    I have three 43 Thrulines and they all look like the one in the first picture with those style clamps.
