Perhaps looking at the serial number tables would give you an order of magnitude up to the point they went with date codes.dusty wrote:It would be neat if we could get a feel for how many Mark 5/vs there are still available to be called into service. It would even be curious to know what the 600,000 number really is. I read it as the number of Mark 5/Vs that have been sold from day one to now but who knows for sure. Not I.
Edit: I did a quick look and calculated 317,983 Mark Vs sold until 1987. After that, it is anyone's guess.
