Sinewave
I have had a look through my archives, but no sign of 5170-853 or 5170-206. I know i have them in Microfilm form, but i waiting to have those 75,000 films scanned..... it its approved (£15,000 job).
I have no idea why the instrument lack any serial numbers. I have a number of model 8 of different varieties that do not contain any serial numbers. I assumed these were used for engineering testing......maybe some of those type of instrument got out in to the big wide world!
