Matt has these maps all correctly positioned !!
There is a fair bit on Deiner on the website link I gave.
In 1956 he was timed at 186 kph (116 mph) on this Velo 250. Thats not bad for a 250 Velo at that time. Deiner was obviously a world class rider as well as an engineer and he beat Fergus Anderson on the works Moto Guzzi when they came to Australia.
The Eldee 2 is now owned by a mate of mine Phil Price in NZ . Phil also owns a couple of KTTs and the Joyce Brother's MOVs. Phil rides a Joyce Brother MOV and Chris Swallow rides Eldee 2 in the NZCMRR meetings. The bikes are looked after by another friend of mine Nick Thomson. Nick and Phil have been playing with Velos since they were teenagers. The Velo in this clip is Nick's Venom ridden by Chris Swallow. The Dommie, Im pleased to say, is mine, ie the bike that wins

ridden by Tony McQueen. Tony is not a bad rider ;-)

This is them at Wyndom. Tony dropped it at the last corner.What you cant see is that they were passing a lapped rider who moved over when Chris passed him and Tony had nowhere to go but straight ahead and down.

Eldee 2 was built by Deiner when he couldnt get back his original Eldee 1 which he sold in the 1950s. Eldee 1 had a light weight Manx style frame that he made himself but when he came to Eldee 2 he was getting a bit old so to save time he used a Norton International frame and Roadholder front forks. For a 250 Eldee 2 frame is a bit heavy. The motors are MOV cases (now Mac) with shortened Mac barrels, Head and rocker cover timing cover were cast in Oz. Crank, cam timing gears, cams etc made by Deiner. Yes it is a gear drive DOHC. When Nick got the engine it had been a bit in the wars so he has been through the motor plus redone all the guides, valves etc, remade the cams and is in the process of remaking the timing gear train. The bike has proved to be reliable and is really fast. Deiner did a good job on head and port design.
One big advantage we have is that Les Deiner was also good mate of a friend of mine in Adelaide and Deiner's widow left him all Deiners tuning notes which have been copied and sent to NZ. He also owns Deiners last push rod 250. He used to travel to meetings with Deiner toward the end.
What seems to be true is that in the 1950s there were a collection of Australians who were building very advanced 250s. This group of people had some of the best bikes in the world in that class.
My friends have been racing old bikes for almost 40 years now and Eldee 2 has been a real surprise to them. It is really an outstanding machine.
For those who think an old bike like this shouldnt be raced my Ozzie mate says Deiner would have been as pleased as hell. He says Les will be up there somewhere jumping up and down every time it gets the checkered flag - Nick knows how to look after a bike and Chris is a Manx podium rider - they will do him proud !
