I can't call these out by brand, but two I notice and somewhat recognize. At the right of the photo is a generic type of "vest pocket" pipe with a stem that folds around to make it more compact and to protect the stem from getting snapped in your pocket. A number of pipe makers produce these, and I think they always sell pretty well because they've been around for nearly a century. I tend to suspect that they are not great smokers. Many people own them, but few claim to use them on a regular basis; they seem to be a sort of popular novelty pipe. Usually the chamber on these is fairly small.
The upper pipe in the pair of pipes the case is meerschaum-lined. This was a popular pipe design in the fifties, and these are still made and sold quite a bit, though many prefer a pipe made entirely of meerschaum, the carved white sea-foam material.
The two pipes in the foreground on the little stands seem to both have plateau on their brims, the rough surface that occurs naturally in the grain of some briar. This is usually regarded at a plus, an attribute.
All of the pipes look reasonably clean and well-maintained, but without being able to inspect them in person and read the stamping, I'd look for a pretty good deal on the lot, and/or more information about the stamping and their condition. The pipe on the front row to the left has a stem that is akimbo. It might just be straightened by hand or it might need at least minor repair if it is a screw-in stem.
If the price for the lot is especially good, and you really like the looks of the pipes, it might be a fair gamble. Otherwise, I'd ask a lot of questions and look for an especially fair price.
