Aldis Scope Elevation Range Dial - Bottom Half Help

[Roger Payne]

The likely second pattern in Post 12 also has an unusual feature, which I would suggest in this case is probably an oversight on the part of the engraver, rather than an attempt to hoodwink - note the extra digit in the srial number; 683,000. I would think the final zero was an accident, & the scope is probably 68,300.

It would also fit that the scope in post 14 was fitted with the Bartle/Modified PPCo rings as the focussing collar & helix in which it rotated required to be moved from the top of the scope tube to the side - as seen here.

I think you are correct Surpmil that the range grads were only engraved onto the range dials following test shooting at Bisley or Hythe (don't quote me on ranges, though!).
