The best luck I've ever had is from the seller mentioned in his post 32 at: Bearcat III - Missing Antenna
I've had my share of bad crystals from eBay sellers before! Yes on testing the remaining two VHF crystals if you can find a transmitter to test them with.
I did not realize that's how you listed three of the six you listed. Now I see you listed those as the actual crystal frequency before subtracting 10.8 for low band use. I can't recall if the old BC-III models used the funnel shaped telescopic antenna nuts yet or just a plain old nut.I asked about the crystals you listed as two are in the channel 2 TV range between 54 and 60 MHz and one was just below Ch2 TV. Those were all 6-32 and if that's the correct size, it should screw into the antenna socket on the board of your BC-III easily for sizing purposes. You could probably figure out the size pretty easy if you have a screw from say an duplex electrical receptacle or light switch that was used to fasten the receptacle or switch to the box. I still can't remember if it was 4-40 or 6-32 but I doubt it was metric as I never really had to mess with any metric stuff back in the late 70's or early 80's. I had that 220 open a while back and noticed I'd soldered a nut in the old funnel shaped nut's place directly on the PCB! They were aluminum and somehow I'd cross threaded mine and ended up ripping it off of the board.
I once buggered up one those old funnel shaped threaded antenna sockets they used on a lot of the newer Electra programmable models like those from the old BC-220 era. And they were perfect as one was VHF-LO and the other had both VHF boards installed in it from the factory. They had very cheap buy it now prices as well which I don't recall anymore but they were cheap. I'd found the old unopened BC-III's on an eBay auction a long time ago. Yes, I still use a pair of BC-III's today for our VHF Low Band state patrol's backup system and another for some of the local VHF High railroad frequencies.
