Here's another question for you.

Just picked this one up, couldn't resist.

On the older Mk5 Nato units, were the serial numbers ever like this? The format is usually different. There's no date on this one either. It's even different to that of a 'regular' Mk5.

The serials would usually have a number followed by another one with the prefix M. And the model on the label would usually say TS1 or MRTS.

I wonder if this is how the first Nato units were done or if it's got a different back on it?

I can tell it's one of the older Mk5 Natos, by the front panel as the later ones had the lines and marking for switching to OFF and DC for transit.

Thanks.
