This auction is for a Vintage Millers Falls No. 61 Yankee Ratchet Screwdriver Pat'd March 30, 1926.  It is in very good condition as shown in the photos.  A flat head bit is included.  

According to Google AI, Millers Falls Model 61 is an earlier designation for a spiral ratchet screwdriver, while 61A is an updated later production model that transitioned to improved manufacturing standards and plating.  Seems like you see more 61A models on eBay compared to this earlier 61.
