Martin Handcraft Imperial/Dansant - pretty interesting horn. Dates to 1933 and has the same design configuration as the Handcraft Imperial. The bell however has Dansant engraved on it (it's definitely not a Dansant) - but it's the same as the Imperial/Standard bell. Bracing is slightly different and more akin to the HC Standard. Has the reversed tuning slide like the Imperial/Standard/Committee models and the 3rd slide throw (earlier models did not) I suspect this is a transitional horn.
