      Thanks Dave/Fred


      I've wondered about the possibility of a Martin Jr existing with the T bar as the time period overlaps, theoretically they could have been made I guess.


      I have a JR with a U damper but other hardware is what one would expect for a JR, I suspect its been retro fitted with the U damper :-(


      Cheers

      I have a list of 136 Juniors, and I don't recall any with the T-Bar damper.

      Vibroplex wasted no parts.  The T-damper came from the X keys.  When they discontinued the X keys, they still had a stock of T-dampers, so they used them until they ran out.  It is that simple.

      What wasn't so simple is the boxed dash lever.  the so called "improved" dash lever was introduced along with the D lables in about 1920.  the improved dash lever was a manufacturing improvement, but arguably not a functional improvement.  Apparently there were some of the box levers remaining at the change over because a few reappear on #6's in 1939, and again on Standard Radio (Air Force military order) bugs in 1943,  but only the earliest ones made.  They seemed to use up the last of that NOS for that project.

      Thanks Fred & Dave, 


      Might as well go on with 2nd question then :-) The T bar style damper, It appeared on #4s and Originals (as well as X) around 1920s, the period overlaps with Martin JR production, so the question is are any examples of Martin JR bugs with T bar damper known to exist? either as a 3" original or a #4 on a wide base?


      Cheers
