Tenebraex Covers for Schmidt & Bender

Good afternoon

I have purchased an ex-mod S&B scope (former L17A1) 3-12 x50 and would like to purchase some covers for both the objective and ocular lenses. I have simple Butler Creek ones for my SB 6×42 but quite like the look of the Tenebraex ones, but need some advice please.

I’ve attached what is currently fitted to the ocular lense as it looks very similar to the mounting ring on your sight. Is this the same design as the mounting ring shown on your page?

I have measured the diameter at both ends but my measurements (ocular end diameter = 42mm incl the knurled rubber ring & obj dai = 57mm) don’t match any options, which makes me think it’s not a physical measurement of the diameter of the scope but is more about the lense diameter, which I only know the Objective one as its 50mm.

What are my options please for covers and more importantly what sizes should I be ordering for this scope.

Thank you in advance

Yours aye

Paul
