That's a very pretty scope. Only one missing knob. A little dirty, but it should clean up nicely.

I'm not sure that I can notice a missing knob, but there again, I am not familiar with these scopes. What I do notice is a missing fuse-holder on the back of the scope.

Bidding is picking up so will be interesting if anyone on here is the winner. I see the seller has put their mobile phone number, for anyone from outside the UK you can ring it by changing the leading 07 to +44 7, where + is either a long press of 0 on your mobile or your local country international access code.

I see it was made in Guernsey which is nice.

Too far away for me to offer to be your scope mule :-)

Colin,

The missing knob is one the left hand lever switch. It's not easy to see. It's a minor flaw.

As well as the modified mains voltage switch arrangements, I note that it's
had a different mains connector fitted. These mods are presumably part of
its military history - looks like it's served time at RAE Farnborough (the
Royal Aircraft Establishment).
