I posted this at Batlabs, and I wanted to see if anyone else may have an answer. At last the time has come to disembowel 150 or so Spectra RR radio's. While taking the MLM out of one I noticed that the RF chassis was painted Orange as oppose to the usual brown or in most cases not painted at all. I am trying to determine which dates which color was used. Any ideas? I know it is trivial, but I see that there is a lot of interest for ODD Motorola products, and this could be one.
