Golf Bravo Zulu,
regarding the pyridine ( please excuse original spelling) additive to the water meth mix, this info originated from a Handley Page Maintenance Manual circa 1970's. The mixture came in 50 gallon drums ready mixed, so I have no experience of the contents. There are a couple of spec.references that I have come across, RR Spec MSRR9859 and D Eng RD2491, but as yet I haven't found the documents.
Any boffins out there with the answer?
Regards
