I've threatened to buy this rifle:

It's quite an unusual, but nice concept. My gripe is since these photos were taken, one side of the action has acquired some rust.

I've also threatened to buy, but I think it's got a #4 barrel and the seller doesn't answer emails about its weight. A .38-55 need not be so heavy, IMO.

One of the modern Low walls, rebored to .30-30 would also be cool as heck. A little more slim than a Ruger, but still strong enough for warmish loads.
