Mark V-B

Since two others have posted about their Mark V-B in the past week or so, here's mine - and a thread where we can accumulate data points about the -B designation. It's a 1984 model 500.
Hi,
I have 3 machines I can look at, so if this data is helpful in find what machines do NOT have a "B"
1976 plate says MARK 5 and uses Vandaila OH as the location
1980 plate says MARK V and uses Vandaila OH as the location
1991 plate says MARK V and uses Dayton OH as the location
The tool history has a serial number 190000 as the beginning of the 2-bearing quill, as of 10/1984. That is close to your date.
