Gas Trap Closed Vs Open Arrows

[Arnhem44mad]

At which serial range did SA begin using the closed arrow Windage and Elevation Knobs?

I'm trying to figure out which toe would be accurate for an M1 seial 18,500 range.

Thanks!

Hi Scott,
The elevation cap should probably be the open arrowed version marked C46002. The windage knob should the standard early version. The pinion should also be the numbered version as seen in other threads on this forum.
I hope this helps.

Thank you! I wasn't going to go for a numbered pinion as I know these exceptionally rare and for something that will not actually be seen it won't make much of a difference haha!

Open arrowed elevation I can do thank you mate!
