Hi guys, I recently found this tag marked : 10 tons MARK II ref No 4Q/2295 extension piece closed height 6'-0" or 6' -9" DRG. No MG 473 serial No 1120 Manufactured by "skyhi" limited Who know from what this is? Vehicle related?
Skyhi manufactured hydraulic jacks before the war and seem to have also made aircraft equipment. Hydraulic | 7th January 1930 | The Commercial Motor Archive This one must have been huge though. I wonder if it had a bridging function ? I've done some further internet searching....Could it be an aircraft jack from a Wellington ?

Yes I think Rich has it. My first thought was hydraulic jack. Rich has the trade name and link to illustrations. There are many photos of these jacks used by RAF recovery, repair and maintenance units. Some show a plane with a jack under the tail, some show one under a wing. Presumably the plate is off an extension tube. Mike
