Here is a Manzel Brothers Class DA Force Feed Oiler. It seems to be in very nice original condition. I put some oil in it and it started pumping. I cannot hold the pressure back with my thumb over the outlet. The output is adjustable with the wing nut. The top sight glass has a very tight crack, I wouldn’t change it out but it would be easy to do if desired. Check out the pictures and see if it something you need! For questions 419 789 1159. Top sight glass cracked but that shouldn’t hurt a thing. Great shape, seems to work just as it should. T he mounting holes are about 6-1/2 apart on center. Weighs 12.5 lbs before any box or packing material. Thanks for looking at this listing! If you want to check out my reputation and such please feel free to google search my name.
