Yes, and was the service guy from 1977 till 2005 when I retired. My area was UK and Ireland all the time and in times of headcount stress the territory included Scandinavia and twice it included the USSR, interesting times.

The products you mention were very rare here. I have seen a XA series only once and that was in the Irvine (Scotland) plant in late 60s, same with the Monomast , no lateral carriage stability, they were both factory hacks; Lewis Shephard, QN QC never, KE Karry Krane rare; an early KK chain drive, once in a marina. The Irvine plant (closed 3-4 years ago) KE was donated to the Irvine maritime Museum.
When offices were cleared and I was around I saved many items from the bin including Inst Manual / Parts Lists, RT 150, YT-40, VT-75 ; not much use but nice to have.
