WWII No4T SCOUT REGIMENT TELESCOPE MKII – EXTRA EYEPIECE

[Bindi2]

Son I have no idea if you have missed any thing I would like to know every thing you do. So it is possible just to slide the High power eye piece into any Mk2 scope and use it no screws no tools just change and go.

Mate, I just grabbed a couple of telescopes out of the cupboard in the next room and pulled them down on the kitchen bench. Took a fitters attitude to it checked everything relevant.

Trust me, I was surprised about the interchangeability of the bits. I would have swore they were different from scratch. I suppose any lens group... (hang on, time to start using correct terminology here).... "eyepiece cell" that fits can work due to the slide- focus being almost infinite in these telescopes. Yes, the eyepiece cell with the eyepiece and shutter (attached in one unit) from the GS telescope will screw straight into the TEL SCT REGT and give good vision. I don't know why you would bother with the HIGH eyepiece cell though. IIRC the HIGH cell gave only x22 and the TEL SCT REGT was x20. The eyepiece cell from the SCT REGT will go into the GS and the eyepiece will screw on to retain it. This was checked between a 1918 RJ Beck GS MkIV and a HCR SCT REGT.

Peter of course will know much more having had to deal with them as a paid maintainer, rather than a fiddling collector like me. Interested in any other's thoughts and experiences too.

Son, that is brilliant and as Bindi2 says such knowledge and know how. It took several readings of each post to get it through my old finance mind (didn't inherit any of my fathers "fitter & turner" skills) until the penny dropped.

Thanks so much for taking the time over the dissection and photos let alone the text. As I said it took a little to sink in but I went and pulled my units apart and the construction of the additional eyepiece is exactly as you described. Whilst I had previously done so I hadn't seen the difference.

Interesting when you consider how many companies in both wars were producing these scopes to such a consistant standard, with in effect a 2” objective, and a magnification quoted in some military manuals as 20x, and in Part 42 of the ‘Notes on Repairs to Fire Control Instruments’ 1941 written down as 22x with greater sizes being developed post war.

There's five, a couple not mentioned above... These are just the Sct Regt, do you want the GS as well?

Yes many of those already famous for their production in binoculars of course. Photo number two, of the Broadhurst & Clarkson one looks like they did the etching by hand on some soft brass.

This is a very interesting thread. Scopes aint scopes Sol.
