Type Touchdown desk fountain pen and base. The chain connecting the pen to the base suggests it was used in a public setting such as a bank or clerks office.
Product Name "Dip Tip" is the filling system style. It's virtually the same as a standard Touchdown, but because of the circular hole in the feed you didn't have to dip the pen in the ink and fully cover the nib/feed, you only had to get the hole submerged. See photo below of the underside of the nib and you'll see what we mean.
Manufacturer and Year Sheaffer USA circa 1960s
Length 6-7/8 inches (tapered); base, 4 x 4"
Filling System Touchdown filler - working perfectly. We replaced the O-ring and the sac and it's taking, holding, and expelling water splendidly. We'll send instructions on how to use the filling system.
