The nice part with the pins - most of these machines need to be tipped back to oil the parts on the bottom side, and that can be a bit difficult if there are no pins to hold the back edge in place so you can hold it tipped with one hand and oil with the others. Many will only tip back so far, and then stay that way so you can use both hands to oil/clean. So without that, you'll need to lay something down, and then lay the machine over on it's side to oil/clean the bottom. Since these are not light machines, that may be and issue for some.
