No32 Mk1 Elevation clicks

[Ovenpaa]

I have just purchased a No4 Mk1 (T) with a Kershaw No32 Mk1 'scope. (Serial sets it as one of the very last No32 Mk1's)

I have looked at a few such rifles and researched long and hard before making my choice and I am pleased with my 'T'. One thing I never noticed on the others I looked at was the number of clicks on the elevation and windage drums.

Everything I read tells me windage is 2MOA per click and elevation is set in hundreds marked with 50 yard intermediate clicks. Fine but mine seems to have more clicks between the higher elevations such as 80 and 90. I haven't counted them yet.

Can anyone confirm how many clicks I should have between each range. The 'scope on mine looks fine, clear optics and a graticule and the drums are fine with no apparent backlash and nice crisp clicks.

Also I have been advised to return the windage drum to absolute zero when not in use, does this mean numeric zero or fully ACW or even fully CW?

Many thanks in advance

David

Could be you've got a set of my hybrid MkI/2 1MOA index plates in there, or someone has been busy with their grinder...

Oh! not sure if that is a good or bad thing So your index plates are a direct swap for the standard Mk1 index plates?

I guess that would explain why everything is so nice, I can only assume it has been rebuilt fairly recently then. I will count the clicks to confirm this (I am quite happy with MOA despite being a 1/1o Milrad person)

You need to start counting clicks pretty quick............... As without a number, nobody can give you any advice. And exactly WHAT is the 80 and 90 you are referring to? Is this clicks ? or the graduations?

I suggest that a good starting point as the new powner of a No4T/No32 telescope combination are a set of little hardly known books, available from BDL (other retailers are available) that will go somewhere to answer your queries and be a good source of other info too.

Another little annoying point that Mk1 telescope owners notice is that at the higher ranges, the pointer on the index plate doesn't always coincide with the number. To correct this - or at least make it acceptable, the pointer was a seperate part of the index plate that after the point was aligned with the number, was soldered in place. Not a lot of people know that......... Have a look at your own while you've got it handy!

This feature was pretty well redundant on the Mk2 and 3 but was overlooked and continued well into 60's Mk3 spare production, when it was deleted and the point engraved straight into the index plate itself

The graduations are 0 -10 elevation and 16 - 0 -16 windage with 64 clicks elevation and 35 clicks windage and the numbers line up perfectly with the numbers.

Yes, I am aware of the books, I have a copy of the Armourer's Perspective .303 No.4(T) and really hope a copy of Telescope Sighting No.32 arrives in the post soon.

You definately have Mk2 clicker plates in the scope but I suspect that the slight overrun (the extra 4 on the range and 3 on the deflection) indicates that you have clicker plates that are punched out of sintered steel as opposed to machined.

The difference is that the sintered steel plates are indexed/graduated/toothed throughout 360 degrees whereas the machined ones are only indexed through the 32 or 60 click sector. This makes the sintered steel clicker plates interchangeable between range and deflection and cheaper of course. The downside is that now, the sintering process is starting to degrade and they break/crack quite easily.

Some of the half-pitch alloy erector segments that locks the erector into its linear position are also made from sintered alloy and can break easily too. Some are made from machined alloy and brass but just be careful if you are one of those involved in overhauling these things. If you do have one that breaks up and need a replacement, just ge a No42/53 as they're interchangeable (? - but you will certainly need to file it to fit) There is an alternative but.....................

Not a lot of people know that.......................

Many thanks for explaining what I have Peter, the good news is MOA are fine for me (I would have preferred 1/10 Milrad but that would be so wrong for a such a rifle!)

When would such a modification have been made, was it down to an armourer swapping the index plate to a newer version at some point to suit the user or was this part of an upgrade process, I have not personally read of such a modification. Based on the serial of 7996 against a build to 8000 for Kershaw is it possible the manufacturer fitted Mk1 drums with the Mk2 index plates just before the move to the Mk2 build?

The 'scope functions very nicely, clear Graticule, zero backlash, positive clicks and very clear glass so maybe it has been through a repair process quite recently and had the index plates changed then.

Do you have any theories on this?
