There are threads on takedowns and the mechanisms. No really detailed photos I think though. Some of the forend removed showing the thread etc.

From a more than interested layman ... I looked into having a rifle like this in 1985 or thereabouts. A Kiwi outfitter Brian Harre was making them on Winchester actions. I would have loved to get one, with three different barrels.

When I bought my Whotworth .375 it was supposed to be converted to a takedown. But after buying it the gunshop advised against it. NO WONDER! John Saunders the seller, sold me a rifle with the thread cut on the barrel at an ANGLE!!! It shot a foot to the side at a hundred metres even with the scope fully wound over. Even experts did not see the angle until pointed out - "what is wrong with this rifle? - when pointed out it is very obvious. Kudu Services fixed it for me, by making custom QD mount bases angled for the barrel, not the action, and with a groove allowing the open sights to be seen as well.

I solved my takedown mania, partially, by acquiring TWO Mauser M03's with four barrels. I want more barrels! Scarce now.

When I win lotto I will acquire a number of custom made Mauser type takedowns with multiple or not barrels.

You have hit on a key point. The best systems are when the bolt locks up in the barrel/barrel collar NOT the action as in the typical Mauser 98 takedwon. It is more secure, and more reliable, safe proof locking in the barrel. The Dakota takedowns did this. A lot of modern action takedowns do this. I BELIEVE some Mauser types are modified to do this. I love the Mauser 98 design. If a M98 was modified like this, it would be very different to the normal M98.

Back to the M98 takedowns.

One system is where the whole action is designed to be removed from a stock easily.

The system above is probably akin to the following.
- the thread on the barrel is "eased" so it can be unscrewed by hand.
- some takedowns utilise an 'eased" full thread. Some have grooves cut through the thread, so the forend can be pushed on, and then screwed sideways a bit to lock it in place.
- there would be a catch, probably underneath, which locks the forend and barrel in place when fully screwed in.
- the barrel is not free floating in the forend. At the very least it is attached to the forend at the rear part with metal work and the catch in the forend.
- a takedown could be a single chambering and forend. Very useful for travelling. It can be carried in a shotgun sized case. Or even in the old days, in a solid suitcase. Excellent for travel on trains, buses, carrying in hotels etc etc, no one needs to know a person is carrying their hunting rifle.
- or a takedown such as this could have multiple barrels, if the cartridges work in the same magazine and use the same bolt head. Modern designs have exchangeable bolt heads or bolts and also different magazines. So I can use a .222 and a .404 in my Mauser M03's.

A downside of takedowns and possibly especially Mauser 98 takedowns is return to zero. Does the rifle return to zero well? Same as QD scopes? Test one's rifle out to see. If a .222 for head shooting rabbits, an inch at a hundred yards may mean missing a rabbits head. An inch on a 8mm does not mean much if shooting a deer. I do test shoot my ,222 usually if putting it back on.

Another more serious concern for the Mauser 98 takedown design is the thread is said to wear overtime. Or could wear. I seriously doubt this is a problem for most people. Unless they play with it, taking it off and on again repeatedly. For a single barrel takedown, really it is probably only disassembled when travelling.

The bolt lockup in the barrel modification avoids this problem.

I love the idea. When I win Lotto I will have made several custom rifles and barrels.
