Photos clearer if you tap on them.
These are the only two photos I have of this machine. I have not cropped them but they could do with more detail. Date is thought to be early 1930s. Dad also ran a two stroke Baker in trials at this time but this bike engine somehow does not look like a two stroke. The frame is very light for the size of engine. Twin exhausts starting high up. Looks like an oil tank? Unable to make out the tank logo, the photo is not fine enough.
Interested in any opinions.
