Victor Rigid Arm reproducer question

[melvind]

I have always believed that all rigid arm victors came with the smaller concert reproducer for a rigid arm. However, recently I have seen two rigid arm machines fitted for an exhibition reproducer. There is metal piece with the slot that allows the exhibition to connect attached to the arm.

 

My question is was I correct that all rigid arm machines used the concert reproducer, or were some late ones fitted with an exhibition? If not correct i suppose someone modified the scissor arm to have the fitting for the exhibition.

 

I'd love opinions and/or answers from many on this forum that are more knowledgeable than me.

 

Thanks
