For those who maybe interested, there were only 10 EJR's ever made.
I am told that there are maybe 5 that still exist.
The owner of the one in the picture, Watabane San passed away 2 years ago.
Footage of an EJR/3 at Mortagi is Uemura San,I saw this machine in Japan in 2013.

I'm guessing the 10 would be the early blue and white ones and the later red and yellow ones combined? Do you know if the yellow and red one in this photo was shown in Europe during the past 10 to 20  years?

The "30" in the background of the top photo is a 1969 or 1970 Jamathi, probably 1969. Jamathi scored several GP wins in the late 1960s and early 1970s, though never won a World Championship.

Gerrit
As a side note, Members should be made aware that 50cc racing is still hugely popular in the Netherlands. Maybe you might be able to post some links to 50cc races held in the last few years.
I have also heard that there are a couple of 50cc Tohatsu/BS racers to be found in the Netherlands. Gerrit, maybe you could verify this.

There is definitely at least one running 50 cc Tohatsu twin in the Netherlands, but no Bridgestone 50s as far as I know. The only Bridgestone that was imported into the Netherlands was the 175 Dual Twin, and only for two years. Several were converted to 125 cc, the most famous and successful being the one converted and raced by Jos Schurgers, who won the 125 race at the 1973 Belgian GP. Apart from the crankcases and a few other parts there was litle original Bridgestone left, however. The crankshaft was designed by Jörg Möller and built by a specialist in Germany (presumably Hoeckle), with a 43 mm stroke. Cylinders were based on Kreidler race kit parts with porting also designed by Möller etc etc. The frame was based on that of the 1971 van Veen Kreidlers.

Here's a vid of the Tohatsu; there's also at least one 125 Tohatsu.
