I just picked up two more barber poles, I have a Marvy 55 serial #2327 made december 15 1951 and the two new ones I picked up were Marvy 55 serial # 7200 and a Marvy 405 serial # 62417. Do you think their serial numbers run from day 1 with the serial numbers all going up no matter the model number or all model numbers started with 1 going up from there?
