LGS has one. I'm developing an interest in these after watching A Bridge Too Far again a few weeks ago, but I know very little. I forgot my reading glasses so I couldn't see too well, but I saw very little in the way of markings. It what I would call the ladder sight, which I've never used. The stock was solid, well used. I know pictures would be needed but I was in a hurry. What should I be looking for? Price was $550.
