      That's interesting, Dave.  I do have one (a Junior) that is in near new condition.  Most were heavily used by professionals as they were special order keys for the purpose of being carried to work in one's coat pocket, by ops for whom the #4 was just too light on the desk to stay still. 

      mine is one of two, almost adjacent serials, with chromed (not nickeled) hardware.  I know that mine was special ordered by a professional telegrapher as a Christmas gift for his 12 year old son, and I am betting the other was ordered at the same time for some other professional's kid.  thus mine never worked for a living, either, eventually passed through several generations until sold to me.  it is about my favorite bug to use in part because it is so handsome.

      Michael & Group,

      As for you latest question, I have examples of the three keys you mentioned but have never seen a Martin Junior with T bar damper. It is possible that one exists somewhere but in collecting Vibroplex for over 25 years I have never run across one. I have kept a listing of T bar damper keys for several years and they are rather common on Originals but much less so on #4's. One of the most interesting keys in my collection is a #4 on a 3 inch base that was put into a glass dome trophy case when new. It was probably special ordered for the OM for a retirement award. I haven't seen many Vibroplex from that era that were truly in new condition.

        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 :-(

        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.

        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
