Hi everyone, getting comet ready for spring l thought l would check gearbox lubrication, after removing inspection cap & dipping all l got was a little blob of oil/grease on the end of the rod, l have two manuals which give conflicting advice the 1st states gearbox was pac,ked with grease when new, the 2nd manual states after 1951 the gearbox took one & half pints of oil my comet is 1953, l can't see a drain plug om mine there is very little of any thing in mine, any advice would be appreciated, thank you.
