All our scopes are genuine military issue MKII scopes with original leather case, cleaned, serviced, excellent optics and ready to use:
The MKII Scout Regiment Telescope was first introduced 1939 at the start of WW2, and soon after supplied as an integral part of the snipers No4T kit chest issued alongside the Holland & Holland modified Lee Enfield No.4(T) snipers rifle, matched scope, officers prismatic compass, etc. The 20x scope proved exceptional at acquiring targets and locating other snipers.
Examples of scout regiment MK2 snipers spotting telescopes always bear the British Military broad arrow stamp on the brass draw eyepiece barrel, together with the model number, maker and serial number. The optics should immediately strike one as excellent.
The most common manufacturer was Broadhurst Clarkson. However, several other optical instrument manufacturers made the scopes to the military requirements, notably HCR & Son (H C Ryland & Son Ltd.), KEC (Kodak Eastman Co) and HBM Co (Houghton Butcher). We have had many pass through our hands, and in my opinion, there is little difference in optical quality when dealing with a genuine telescope. I have noticed the magnification can vary slightly, to my mind, between 20x and 22x, with the KEC scopes tending to be slightly lower magnification with the knock on optical trade off of a little brighter image and greater depth of field.
The MK2 snipers spotting scopes produced during the war remained in service alongside the famous Lee Enfield No4 MK1(T) sniping rifle. In c1970 these rifles were updated by the Royal Small Arms Factory (Enfield) to fire the 7.62 x 51mm NATO cartridge (besides other upgrades) and designated as the L42A1 Sniping Rifle. The Scout Regiment Telescope MKII spotting scope continued in service as part of the British snipers kit accompanying the L42A1 sniper rifle. Towards the end of service the scout regiment became known as as the Telescope Straight L1A1 (not to be confused with the TEL. STRT. STG. L1A1 O.S. 2429 G.A, the new sighting scope for the L42A1 rifle!!).
Furthermore, some time after the introduction of the L42A1 the original old style leather cases were impressed with the mark 'CASE TELESCOPE SCOUT REGIMENT' or 'TELESCOPE STRAIGHT CASE'. Around 1980 all new or replacement cases were of the new green plastic type. In summary, unmarked cases can be of the No4 MK1(T) and L42A1 era, while those stamped are usually from the L42A1 era. Obviously the green plastic tubes are from c1980 onwards.
Unfortunately, reproduction/fakes do exist; however, genuine telescopes (amongst other sure-fire signs) are the only ones to have pin sharp optical quality at critical distances, which will be obvious when first focusing. An unclear image or one that cannot be focused is usually the first warning sign. It is important to remember that these scopes were in military service and therefore subject to maintenance from skilled armourers, who will have been resourceful maintaining these scopes for their intended use. One should not confuse an official armourers service/repair/modification (to military approved procedures) with an unskilled cut and shut that is becoming all too common with these scopes. Ideally, some of the original bluing should remain and not polished back to the bare brass. These telescopes were never originally issued in bright brass; I can't imagine how useful a sniper or observer would have been if this had been the case. The telescope bodies are either leather or thermoset clad, the waterproof cladding usually later than leather versions as suitable leather was in short supply towards the end of the war, although the leather cladding became popular again post war. Optical performance is preferable to cosmetic condition up to a certain point.
