HI James,The brum Scott in your latest picture is very interesting to me as i have no data on it in my register. The Frame Number (S 1104) is mid 1957. I can not read all of the engine number,DPY 54_ _, can you see the last two digits? This is the first “new”Brum I have located for many years!. Was it registered in the uk as VOC 956, engine no. DPY 5453 ? The position of the frame no (on the headstock gusset plate) has been seen before,but the usual location is nearby on the frame tube.
