G'day P/D's. Searching the shed today for suitable container to hold oil for the steam engine, to no avail. Check indoors and located a printer ink refill bottle. Just the bees knees, holds about 20ml. squeezy sides, stopper cap to prevent leakage if tipped and long slender nozzle for getting into tiny oiler cups.

Hope it solves problem for others looking for suitable device.
