I just picked this up this morning at a yard sale. I couldn't find a whole lot of info on it online, so curious if anyone here could help. What model Shotwell pump is this? There's "850 Gal. Outside 1st. ???" hand painted on one side. The decal on the front isn't very legible. I appreciate any help or info you can give. Thank you!
