The fact of Lee’s departure is known, but not the date.
Lee pipes have three distinct eras.
The first have deeply inlaid 7 pointed stars on the recessed screw stems.
The second have deeply inlaid 5 pointed stars on recessed screw stems. Polishing I think is slightly better. These are not common.
The third have stamped stars with gold foil impressed in the star, that quickly runs away. Early stamped stars have recessed screw stems, later ones have Kaywoodie type exposed ring screw stems, and the last have cast push stems.
From first to last every Lee was oil cured, had a removable Lee stinger, and except for the very first pipes, were marked as a Limited Edition.
I used to think the editions were limited to how many orders Lee had for that shape in the catalog, but I’m not so sure now. When I get a Lee I remove the stinger and put them in a box, and I’ve noticed that it’s rare that two stingers are exactly the same. I’d like to think there was an operator at the Lee factory that machined a certain number of stingers and then slightly changed the settings on the machine, thus making each run a limited edition.
Lee advertisements said to Reach For The Stars, symbol of the World’s Finest Pipe.
I can’t say a Lee is the best pipe on earth, but I do think none smoke any better, last any longer, are any better constructed, break in easier, and by far Lee had the most beautiful and distinctive counterfeit resistant trade marks ever placed on a briar smoking pipe.
And at least the early Lees had hand cut stems, here easily seen on this 7 pointed star Three Star Lovat.

Every briar pipe, is really just a hunk of wood joined to a rubber stem.
None are better, than the ones Lee made.
