Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums Petroliana Value Questions Wayne pump value and number

I have a Wayne pump which may be a 851 series from the 1930's and wanted to confirm that's correct. I also wanted to see if I can get a value before I look to sell it. It is an older restoration and the internal pump and such are no longer inside. I have attached some pictures for viewing and any help on the questions would be greatly appreciated.
