Agreed, and as my father in law was an ex 75 squadron man, he accepted with pride the tray of Stirling adapters, having served on Stirlings at Mepal in WW2. Now, I'm no expert, but were the Lancaster, Halifax and Stirling hydraulic systems OF4 (vegetable based oil) ? As opposed to the modern OM15 etc mineral based hydraulic oil. Anyone know ?
