what is it

[hubops]

Hi All ;

I noticed this item at a local auction - link below - and I have no idea what it is.

It's wide-open not necessarily related to woodworking ; not necessarily complete ..

Any guesses ?

Looks like surveyor's gear.

Looks like a pair of simple transits - Likely used for installing farm frainage tile
