I have a local flea market nearby but haven't found any good pipes there for years. I did find 12 Sixten Ivarsson pipes there several years ago, though! That really made my day! :D
At another large flea market this year, I was very lucky to find a cased set of Dunhill pipes. Or rather: one of the pipes was missing but luckily the other pipe was present: a Dunhill "Mini Magnum" from year 1929/30. It's basically the same shape as the famous "LC" but with a slightly less prominent "swan neck" stem. Quite different from a shape 120, though. I emailed Rich Esserman the pictures of the pipe, and he confirmed that it is a "Mini Magnum"... I got the pipe for DKR. 450 (roughly USD 80).
I was thrilled to find that "Mini Magnum" since I also have an unsmoked (and cased) "Pocket size" Magnum from 1926(despite the name, it's larger than the "Mini") plus a cased "Full Size" Magnum from 1924... the full size is 7.5 cms in bowl height and is 25 cms long (shape is the classic "Bent" with a hint of "LC"). The bore is 25mm
