I need some help indentifying this piece of equipment
(OP)
I work for a small Geotechnical and Construction Materials Testing company. We just obtained this piece of equipment in an acquisition of another firm. The tips in the second picture seem close to Dynamic Cone Penetrometers, per ASTM STP-399, but I have no idea the function of the double gauges. Any help would be greatly appreciated.

This equipment is still in use in Europe where SPT is not used at all.

These tools were used for soils investigations before the introduction of the electronic cone.
The gauges were used for measuring how much pressure was required to seperately push the tip unit and the friction sleeve into the soils.
Detailed notes, a system of inner rods and an extremely patient and skilled driller were needed in order to collect soils data.
In the day, this was cutting edge equipment, but I don't think many people (if any) use it any more.
