Jeff (transamcuda) has been having some health issues.
Mark (aarchives) moved a couple years or so ago. He emailed to let me know he was going to get the registry fired up again about a year or so ago, but I have not heard from him since.
I hope things are going well for both of them.
I do keep track of the AARs in the 1970 Hamtramck Registry, I have 1468 of them recorded so far. There are several loose engine waiting to be matched up, a couple of transmissions & several broadcast sheets & other paperwork too.
