Kaywoodie 7650

I posted this to you yesterday, but I'll do it again:
If you do a search for Kaywoodie you will find a lot of info. But I'll give you some info to start. This pipe dates to the period between 1929 and 1931-2. Later than that and you don't have the "Patent App For" stamp as Kaywoodie received its patent for the synchrostem in 1932...or maybe 1933, I forget.
Rock Ambera refers to the faux amber stem. I'm assuming that the stem has a black clover on it.

At the time this pipe was made, Kaywoodie was one of the most popular makes in the world. It outsold Dunhill and cost more than Dunhills of the time. The quality of their briar, which was air cured from old growth Algerian briar that was claimed to be 100 years old, was second to none.
Kaywoodies are highly collectible, but that does not translate to high prices. Because later product was reduced to the status of a "drugstore" pipe, and because S & M Frank, who bought Kaywoodie in the early 1950's, outsourced manufacture to Italy in the 1970's with very unfortunate results, collectors have downgraded the pipe and seem to have forgotten that it was once a very high grade make. That state of affairs is improving, but not by a whole lot.
The other factor is condition. A worn out pipe, not matter who made it, isn't worth a lot of money. But if the condition of your pipe is excellent, and the shape is a popular one, you could see a high 2 to low 3 figures for it. Most Kaywoodies go for $25 - 70. A very few, really rare models can go as high as $175-200. But those are from a slightly earlier period than your pipe.
Post some pictures. There are some real Kaywoodie experts here, but they will want to see images.
