Periscopic Prism Sight Repair

[Terrylee]

I was recently given this early Periscopic Prism telescopic sight. Unfortunately the cross-wire is missing. Can anybody give me advice on how to replace it?

PM me with your E-mail address and I'll do you a step by step photographic strip down for a PP Co scope.

Cheers,

That may be only a post type scope.

hey Simon, why not do a photographic breakdown for the Forum, as I'm doing with the No32 sight over the next 6 months or so?

What's the availability of the .001" crosswire. I am using .0008" platinum as I can't get .001 anymore.

Peter,

If you think there would be enough interest I could do one for the Aldis too?

.001 wire is still available in the UK I'll dig out the details of the place I had some from last and pass it to you.

Cheers,
Simon.

There would DEFINATELY be a demand. I have got sufficient .0008" wire. Don't forget that I have Patt 18 ocular lenses too

0.001" platinum wire is available in the states, but I've not purchased any since Mr. Laidler specified 0.0008" diameter. So what was the original size? (percentage-wise the difference if pretty significant.)

[Peter Laidler]

.001 was the norm for the No32's but the spec for grat blocks, ordered as spare parts after 1970 (intro of the L1A1 I suspect) suggests .0008". It will affect the obfuscation but .......................

I repair using .0008" across the board now

I have 2 PPCo scopes stripped here, one missing cross wire but retaining original post.

The graticule crosswire on PPco scope is not 0.001" thick but I measured it at 0.0025"/0.06 mm thick and appears to be originally Gold wire. See pics, I temporarily stretched some 0.001" wire against original to compare as well and 0.001" wire noticably too thin in my opinion.

I don't have Gold or Platinoid cross wire in this thickness but do have some Tungsten wire.

Also measured pointer post whilst at it and also appears to be gold and is 0.0095"/0.24 mm thick.

It's all a bit academic really because the cross wire is there simply to prevent the sniper canting the rifle. If he was REALLY clever, he could use it as a means of judging range, but not a lot of them went to the front with their old school log tables tucked into their sarnie bags ...., that's 'tucker' bags to you wild old Colonials
