Something I just thought of.

One of my 318's is a TAKE DOWN but a very invisible one,
built on an M17 Action and the T/D system is the same as the H&H system of action / barrel comes out of the stock.

I don't have photos of it but a mate missed the gun 20 years ago and when it came up for sale a few years back, gave me a "heads up" on the gun and to make sure I bought it as the desciption in the catalogue didn't say T/D so no one else knew or picked it during the inspection day. I was so wrapped to get it.

I have since found out that their is an identical WR gun in 425WR so the gun has been promised to the owner of that gun
which will make a nice pair.
