Help ID this speedometer part

Took this from a 1959 60 Series Viking Task Force (Boom Truck). Any idea what the piece on the back of the speedometer is? It is screwed into the speedometer cable input, and is vacuum actuated, and the speedometer cable screws into it. What is it, and does it have any value?

I would guess that the truck had a two speed axle and the speedometer drive shifted to match the axle ratio.

It would be an extremely hard to find part but the buyer may be harder to find

Re: Help ID this speedometer part

Thanks guys. Now, another strange question....The instrument cluster, where the speedometer cable would normally plug in (but currently has the 2spd adapter connected), when I removed the 2 spd adapter, there was a male end coming out of the instrument cluster, requiring a FEMALE end on the speedometer cable. Sound strange, or is this how all of the TF clusters are?

Re: Help ID this speedometer part

all clusters i've ever worked on had more or less the same connection
should be the same end on it as the adapter
