As far as I know, nobody is making the 1915-16 oilers. So Glen, RV, Bob, why isn't one of you doing these? Not enough demand?
It may be because of the difficulty involved in installing them into the spindle bolts and tie rod bolts. That little spring needs to be anchored down inside them somehow.
I'd buy a set....
Mike,
From memory -- that is dangerous -- the man-hole cover oilers that were on our 1918 popped out similar to the later spring loaded flip top oiler that replaced them. The cover stayed on the insert and it was a unit and would work even when it was not installed in the spindle. But note that Trent at one time had a note on his web site (has not been up for a while) that some of the spindle bolts around 1915-16ish had the oiler machined into the spindle bolt and the lid was then attached.
Manhole cover oilers on tie rod bolts – see http://www.mtfca.com/discus/messages/331880/336413.html?1358871041 and back in that Jan 2013 posting Jack mentioned he still had a few of the manhole steel (not brass) covers available.
Spindle bolt with pressed in manhole oilers the ones I’m 80% sure pressed in as a unit and the lid stayed attached even when they were not pressed into the spindle bolt (that was about 40 years ago… so I may not recall it correctly.) See: http://www.mtfca.com/discus/messages/29/27342.html

Maybe I don't know if you are referring to "Gits" oilers but here is a site for them

My 15 has these man-hole type covers, and if I remember correctly the little spring is held with a piece of wire down in the bolt. The wire has a hump in it to hold the spring in the center of the bolt and it goes into a hole on either side of the bolt to keep it in place. Seems as how I put the wire in first with the spring attached, and then pulled the spring up enough to hook the cover on to it. Then let it all snap back into place. Does that make sense?? Regards, TDE
Tim -- Those are like the ones I've seen. But as Hap says, they could be made with the spring attached to the bottom of the oiler instead. Seems like that should work and be easier to manufacture and install.
Some research by Trent that Hap has posted before.
The T-2944's that I have seen are intact, as Hap noted, the interior spring that holds the round cap shut is fastened inside the oiler, doesn't make any contact with the spindle bolt.
Picture shows the T-2944 press in 'Man-hole' type oiler.

In my experience the man hole oilers fit in exactly the same way as the flip top type. The oiler and cap come as an assembled unit. The oiler is pressed { tapped in with a small hammer?} by gently tapping on the lid until the oiler is seated.
Hope this helps.
