Here's my 1957 Mk2 International leftie, with its x18 Unertl Super Varmint with calibrated head.
I bought it about twenty years ago from a local dealer, complete with correct P-H diopter sights [front and rear] a Gehmann LH single-point sling and a counter-top plastic box bearing the words J G Anschutz on the lid. Inside were twenty-four sets of Anschutz foresight inserts.* Also in the deal was a well-made wooden box with a sliding top. Inside was a complete [apart from the actual diopter sight] set of Al Freeland's micrometer tube sights on shiny new Unertl POSA mounts. By a lucky fluke, the P-H diopter unit screws in perfectly.
I paid the princely sum of £55 for this lot - then about CAN$85-90.
The scope belonged to our club secretary, Les Tittman. He took over responsibility on my actual birthday, Saturday, March 2nd, 1946. He retired from the post on the same date, but in 2000. He continued to shoot, however, until the weight of the rifle he used got too much for him, and he had to shoot from sitting position. He died in 2004.
His widow could not imagine anybody being interested in his old gun, but it WAS a nice Winchester Model 52D, and got snapped up before I got a chance, but nobody wanted the odd-looking scope. The new club secretary, however, knew his market, and poked it into my chest one club night. 'Make me a GOOD offer', he growled, 'Emmy needs some ready funds'. It even had the very rare tapered scope case in nice leather - never seen one before.
I called up Dewayne Greiner in TX, Unertl maven, and got a good idea of the then-value, and paid the equivalent sum over in £s to the widow.
Everybody was happy.
Nice, eh?
*PS - I sold the Anschutz sight inserts for £30 a set. Almost paid for the whole shebang.
PPS - O DO have the recoil spring, and like the guy you laffed at, I've put it on the scope so that I don't lose it. The scope, BTW, has the much sought-after 1/8th minute dot reticle, and is as clear as the day it was made, sometime, according to Mr Greiner, in 1952.
