Hi brianich, with regard to your enquiry a couple are Cadets and the rest are the thicker walled R/F Martini's. No idea what model they are though. A couple are take downs.
A few years ago the Cadets were about double the price of the 12/15 and have now completely dried up.
Haven't seen one for sale here in NZ for years now.
Probably all those vandals buying them up just for the actions years ago?
I did keep the straight stock on one Cadet that I had converted to 223 because it had a really nice piece of wood and thought it would be nice to keep as much as I could of the original and I think I like this shape better than some of my other pistol grip stocks. Perhaps somebody can tell me what the CMF stands for on the stock. I did used to know but have now forgotten.I do know about the NSW as I lived there for awhile.

At my club range on Sunday, first shoot since Christmas.
Everything shuts down over this period from just before Christmas and into the new year as its the summer holidays in NZ.
It was a boiling hot day and after slathering all exposed skin with 30+ SPF sun lotion as with only a thin Ozone layer screen over NZ you can burn within fifteen minutes if in the sun.
All set to try the tips for reducing my groups into the minute of angle.
During the week before I had tried dry firing with the scope cranked up to 32 power and found that a lot of the trouble was the way I was holding the rifle.
I now just lightly hold the top of the wood where it joins the action with my thumb and also very lightly with my fingers the lever just to get some purchase for my trigger finger.  
During last week I had also had a look at the Double Gun forum and came across a post from the Late Michael Petrove regarding shooting a 22R/F from a rest.
It works, got my groups down to one inch at 100 metres with the silencer on and using RWS Rifle match.
Have a look at the link as I think you will find it interesting.
I think the reference to the 22R/F is on or around page three of the post.

   The late Buddy Streat, at the Columbia Schuetzenverein when they were shooting at Fairfax VA, 3 years in a row shot  5 shot groups under an inch at 200 yd, with a MK II Martini.  Smallest was about 0.85"

I had a BSA Mark three for a while. Shooting it OH was very difficult. Like holding a log out there. Sold it to Bob Bowman. Bob shot many 250's with it. Well, think they were leaded edge 250's anyway.

Win 32-40, sounds about right re. off hand shooting those martini int'ls - after all, Mk III and V were developed as dedicsted prone rifles, so oofhand use would be hard to say the least.  OTOH, a MkIV was the ISU model, so works much better offhand.  Seems like the BSA guys did their homework well.

The Mk IV ISU was intended as the 3 positional was very suitable for that .
I was lucky to know a Shooter who moved here from England who could get the Mintest  BSA Intl's and Anschutzes very cheap, as there was a glut in England with every town having a shooting club , that were generally disbanding for different hobbies and pursuits about 25-30 years ago. With the War fears diminishing, less Government subsidy and less interest. He brought over at least 20 -30 over a 8 year period . I was always getting different ones , trying to find a real standout, and there wasnt much difference in all the BSA Mk3 -5,s and Anschutz target 54's. they were all amazing. The Mark IV was the most common of his offerings and my favorite, as they werent any less accurate. (they must have been most popular) We did lots of Bench testing including weekly in his 50' basement range and weekend and summer eves out doors 75 yd -200 M. all the best target ammo. Eley Black Match was generally the most consistent in all guns.
He never brought MK2 and previous, so I dont know about them

Nice info on MK III
