The Ariel part number is 3121-34 23T 3rd layshaft gear. I haven't got an RE parts list for a Burman box though. Mine are all Albion boxes. is LV7 an AM part number as opposed to the MT for WD? Ron
Hi Guys,
Assuming it has 23 teeth it will also fit the G3 box, but not the G3L (21T).
AMC and Enfield use Burman numbers. 25C is the number for the layshaft third gear, the M3 or just 3 is the version (or mark in Burman speak} of that gear.
I.E. the G3L version is 25C/M5.
Cheers, Mick.
I think it's the 12th. version, second generation, fifth series, 58th production batch of the Mk 19 third gear for a Matchless late edition, 4th pattern layshaft as fitted to an 'M' suffix /27 group gearbox and it was only made between 1.11 and 10.36 pm. on the 18th January 1942 at the Plumstead main works...just after they produced the 3rd. pattern rear stand spring but before the nightshift redesigned the big end... ....Ian
