All NVF's like in Jims's picture use a 15x1 needle. The VF2, VF1, and LAVF, the previous Vertical Feed models, use the "Davis Long" needle, the most common form being the Boye 10. Around 1873 (Pre Davis Improved) and earlier a round shank needle was used which is slighty shorter than the Davis Long. I've only seen less than a handful of machines that would have been made to use this round shank needle, most common form being the "Boye 20".
The Ismacs Needle list does show a "Davis NVF" as using a 15x1, though it is a very long list.

Hi Jim,
Nice looking NVF and a good trade. The extra presser foot lever is for additional lift. This was one of the improvements over the previous model along with the back tack button and 15x1 needle. You'll notice the disc tension on your new machine is different than your later NVF, the later tension system being patented January 1915. I'd stick with SM oil for delicate decals like your Davis. If I'm impatient and not concerned about possible decal loss I use non pumiced Gojo.

I've played with an awful lot of cleaning regimens, but I guess I thought that soap and water wouldn't attack the finish.
I'm looking forwards to locating the treadle parts, that were removed when the head was electrified.

This leaf spring pushes the feedbar and needlebar towards the operator and a roller inside the head pushes it away to give the machine its front / back feed motion.
The NVF is the last model of Davis Vertical Feed so it was never improved upon except by other companies such as Singer.

When you get a chance, take a picture I'm very interested in seeing this. This is the only internal "layout" I'm familiar with
Thanks
Jon

If the feed is not cleaned well oftentimes the rollers will not roll and get flat spots with additional use. Not an easy job though not tough if well prepared. I have read stuff that makes it seem much more difficult than it really is.
