That's the pipe my bride wants me to find. She spotted something along those lines in a Sherlock Holmes picture.
Excellent!
You'll find Calabash pipes in modern Sherlock Holmes iterations - movies and TV series such as
Roger Moore in SHERLOCK HOLMES IN NEW YORK (1976)
Michael Caine in WITHOUT A CLUE (1988)
The Jeremy Brett TV series (1984-1994)
YOUNG SHERLOCK HOLMES (1985)
and even Brent Spiner playing Sherlock Holmes in a Star Trek: The Next Generation episode ELEMENTARY, MY DEAR DATA (1988)
Apart from these few examples the Calabash is hard to track down in the SH movies with other Holmes actors sticking more to the traditional pipes in the straight - full bent range.
Less is seen of the Calabash in the earlier movies and I believe there are only two stills out there from the classic Basil Rathbone and Nigel Bruce 1940s Sherlock Holmes movie showing a Calabash pipe
SHERLOCK HOLMES IN WASHINGTON (1943)
THE SPIDER WOMAN (1944)
Miscellaneous
Conclusion: I find the absence of the Calabash pipe in the novels and short stories - at least after THE HOUND OF THE BASKERVILLES (1902) and THE RETURN OF SHERLOCK HOLMES (1903-1904) - surprising to say the least as the Calabash had already achieved/was just about to achieve fashionable status at around that time . . . also seems to me the perfect pipe for Master Detective Holmes and his contemplations.
