I am always impressed with the items you come up with. I am sure it has something to do with years of experience and getting your name out there as a buyer/seller. Then again I think it has a lot to do with some shoeless horses in your neighbourhood.
Not only is this a beautiful machine it is a very unique item. I'm betting a very early salesman consignment sample which after it served it's purpose was sold off to recoup some money, eventually ending up in a South African collection. Boy the story this machine could tell; USA to Europe (?) and to Africa.
My vote is with the counter weight being added right at time of manufacture as an experiment. Then when the company moved on to other ideas it was sold off, or consigned, as no longer needed but still working so had some value.

Thanks Bruce. Clearly, I should shop closer to home..

. When shipping becomes more than the price of the item....it makes you think.
I received a PM asking why I called the tone arm (travel arm) bi-metal.
Well, I guess pics would help explain. I know George did an excellent job in adding a photo in his first Compendium
showing the ovular shape of the arm body.
You see, the arm body is really a piece of rolled steel (joined by a seam at the bottom) that was then flattened. It was pressed more as you go to the sound box end. In fact, that end is pressed flat and then curled to allow the sound box throat to fit on.
The yoke end is ovular. The front part is made of cast brass and is joined to the ovular end. Creating another seam.
The support arm underneath is also cast brass with a leather pad. Finally, a brass pin was used to hold it all together. The pin that goes into the main support arm is also steel.
So, one can say the arm is bi-metal.
It seems (based on very few known), this arm was changed to one that was simply stamped out of thicker gauge steel. So, it has a scooped out appearance on the underside. The arm support is also stamped steel and redesigned to fit further under the now exposed underside.
Clearly the early arm required far more skill to make and more man hours.
