Hi
The type of grease nipples fitted to the model d is a,"slide on" type grease nipple... You can still buy the slide on adaptor to fit a regular grease gun from the likes of ebay, no problem. The nipples themselves might be a bit more of a challenge but should be available from suppliers that sell bulk fixings & fasteners... alternatively this type was also used until relatively recently on E.R.F trucks (r.i.p) so you could go down the h.g.v motor factor route & try your luck there.... in fact I came some in a box of assorted nipples at work only last week, so the're definitely still out there....
Regarding filling your grease gun, there's nothing to stop you filling your grease gun manually if you have a tub of grease to hand, the cartridge is only there to make a dirty job slightly less dirty....
Good luck Mark.
