|The Öltropfer in use.|
A Öltropfer or "oil dropper" was present on every Rg 34 and was used for to carry the Waffenreinigungsöl or cleaning oil.
This type of oiler was patented by Gustav Appel in 1933. For to drop oil it is necessary to press the bottom (Lüftventil) at the same time that pushes the tip (Tropfventil) down to uncover two drilled small holes where the oil goes. It has a capacity of circa 12 ml (10 ml on phenolic oilers) and to fill the oiler, the base was unscrewed.

At first were made in machined steel with high quality and like the cleaning chain it was a piece with high time-consuming manufacture. At the end of 1941 a phenolic oiler (similar to the metal oiler) was introduced and both were used throughout the war simultaneously. The machined steel oiler suffered some simplification during the war and at the end was introduced also a pressed or stamped type oiler.
