Never been near one, but looks cool, always liked the G85 in a Rickman.

The ESO you show Alison is a speedway engined bike. The one for sale is a genuine ESO scrambler made in the late 50's-mid 60's. Jonesys legendary Black Betty is a Metisse fitted with one of those rare scrambler engines. The difference between the speedway and scrambler engines is the scrambler has a unit construction gearbox attached (plus the speedway engine is a higher state of tune for methanol). Alans got three ESO scrambler engines and has a rare EG ESO roller frame enroute from Sweden as we speak. Betty's currently undergoing some well needed suspension and engine updates for the upcoming title meetings.

Scrambler engine still got a total loss oil system like the speedway one?

No it's got a recirculating oil pump but that's also the engines achilles heel. The pump gears are bronze and prone to failure. Finding unit ESO oil pumps or their innards is practically impossible, calling for expensive machine work to produce new ones.

Frank knows a little bit about 'em Alison but Alan's the real expert. He really knows these things inside out.

His name is Egon Gustaffson from Sweden. He was one of a shitload of innovative framemakers in Sweden during the sixties. The special frame market in Sweden was even more alive than in the UK or US during that time due to some protectionist import taxes designed to protect the local manufacturers (Husky, Monark, Lito, Lindstrom etc). The canny Swedes got around it by building their own unique racers, often using British running gear. The EG that Alan bought has some impressive history behind it and it's noted to be especially light.

A few of those innovative Swedish pre 65 frames are now being reproduced, especially the SOH  frames made by Sune Olsson. He's currently remanufacturing his 1963 designed frame for use by Indian Royal Enfield engines for a low cost entry into the sport. I'm going to order one for my Triumph 500 engine in June.
