hydraulic Turret control - ID required

[Tony Smith]

A Friend has just acquired these boxes of items as part of a job lot purchased, and would like to know what they are from, and to gauge any interest in the items.

The 2 boxes contain a Logan hydraulic turret control, a Logan Gerotor hydraulic pump, an envelope containing the mounting bolts and washers and a quantity of NOS hydraulic hoses to suit. While it is clear they are US manufactured, which tank turret do they suit? There is no date or part numbers on the boxes, but the pump has a model number HTM 2.1.

[Tony Smith]

The hydraulic control unit has 4 ports for hydraulic connections, a rotating control handle, and 3 toggle switches.

[Tony Smith]

Two of the toggles are On/Off controlled by the thumb (of the Left hand!), while the third is a momentary contact operated by squeezing the grip. The are no plates indicating the function of these switches.

The hydraulic control is operated by twisting the grip clockwise or anti-clockwise.

[Tony Smith]

The pump mounts to a flange by 4 bolts (or studs), and is driven by a splined shaft. It has 2 large ports that are the same size as the supplied hoses (Looks like 3/8" or 1/2" NPT/BSP), and one smaller port which might be for a relief valve or gauge.

[Tony Smith]

The hoses are a mixture of flexible rubber and hard steel tube. All appear new/unused.

And lastly, the box has this marking on it. Does this help with dating the box? (Sorry don't need help determining the value the box might sell for if we save the cardboard! )
