It looks similar to the TR-C3 wiper but the shaft is too short for the late 1931 model AA 315A and 330A drop floor delivery and bus applications respectively. The other model A open and closed car wipers are of a different design.
The MAFCA organization made a good wiper PDF document back in 2014 for the Puyallup, WA National Meet that includes all the known wipers used on the model A and AA vehicles. I found it on line some time back but MAFCA has since changed their web site.
