I received a packet of Photos from Don in todays mail, so Dutch and KB 171, here's some good shots of Don's half size JAP.
Here it is with Greg Cameron's ex Bob Baker Wessie
And here's a comparo shot of the motor with a full size JAP timing cover and Pilgrim pump
In pride of place on the coffee table
Don also sent me some early '60s Short Circuit pics, I'll post them up in Slides CDT Images
