Looking for info on the L42 L1A1 scope turrets

[Roy W]

The Mk 3 should have 60 clicks between 0 & 10 and the L1A1 is 48 clicks. That's how I was told to tell the difference (numbers from memory)

If you look closely you will notice the graduations are not the same distance apart between the M and the standard drum.
I have them displayed flat in a file and see if I can show the difference.
Doing that was an interesting exercise with the drum on a mandrels, the camera on the carriage of the lathe and bull gear on the lathe rotated a few teeth each shot.
Lots of fun and the things we do playing with Lee Enfields and scopes.
The ranges due to the tooth difference using the .303 plates and 7.62 are not the same but lose enough.
There is an issue chart showing the correction factors and I have one here...someplace.
Going to get some charts made up ..someday :-)##

Is this the chart you mean Warren?

How strange (and not for the 1st time).

Warrens was the last post showing before I posted the 'chart'.
After I posted another post appeared, made 2 hours earlier but not on view.

Never mind, better to get it twice than not at all.

[Warren]

Thanks guys, I do appreciate it.
Yup, that is the chart.
I have one someplace on my desk as I just had it out the other day and was trying to see if it would photocopy.
I am thinking of send one along with the No. 32 scope "sight in target" I include when I return repaired No.32 scopes.
Just a little added touch..

Good Day Warren and All,
Here are a few pictures of elevation turret. Pictures have been emailed to Warren directly.

Regards,
Michael

Hmm, interesting in that the BA10 locking screw is missing.
I am finding so much hit and miss on the L1A1 scopes I am beginning to think they were overhauled in India by the lowest bidder.

[Roger Payne]

IIRC Warren, PL told me that some of the last replacement drums were not fitted with the tiny locking screw. When I fit replacements I do not fit the screw either, & they work fine. There seems to be enough 'friction' between the two parts for them not to slip.

Hi Warren

Here's a pic of mine. For info it also has "DON/88" in white paint on it. An overhaul date?
If you need it emailed please let me know.
