Model T Ford Forum: Forum 2018: NH-ish carburetor? Knock-off or what?

Hopefully someone can provide an answer as to what the might be. A standard looking NH carburetor from the one side:
NH1
NH2

But now when I turn it around, I am a little perplexed:
NH3

A standard looking Holley NH swayback with a side drain bowl, T6340 in the casting, no tag and no provision for one and a screw-in vent like those on the earlier straight-through NH design. So, is this just an aftermarket knock-off or something else?

Western Auto Wizard?

The Wizard would be the same as a Simmons which is a straight thru carb. I would say just an aftermarket knock-off.

Some aftermarket carbs had a decal on the bowl instead of a tag on the casting. The decals didnít last long if they got gas or oil on them.

After looking a bunch of NH's today, I don't know. The vent was in the same place only covered by the label. Everything else but the label area looks just the same.

Standard early NH. Brass vent no label

Thanks Dean, that was sorta in the back of my mind but the lack of label, was not sure.

So if I am understanding correctly, this was a 2nd generation NH that was manufactured in between the early NH straight through and the "standard" swayback, side drain NH? As much as I have looked, I have seen no reference to this carburetor, that is why I was thinking knock-off. This just seems to be a weird thing to copy (the brass vent screw) and not put any tag or label on it.

Here's an early Model NH with tag, but mounted below the hole for the brass vent screw. Note the tag has same look with the famous large 'M' and the lower type 'odel'.

So, are we saying knock-off, genuine or I don't know? It does seem like a logical evolutionary step between the early NH and the swayback NH. All 3 castings are similar, but different.

Early NH, straight through
straight

The mystery carburetor
mystery

And the "standard" swayback
swayback

Hopefully someone has seen one before or has one floating around and can help with the discussion. I don't know what it is but would like to find out. Oddly enough, this is the only "NH" that I have ever come across that has the original style drain plug that is shown in the manuals.

Gail Rodda's Model T parts Id book show this carb as 1922, from Russ Potter's collection. Does not look to have the label in the photos but does have Ford script on the fuel inlet side at the rear just above the bolt hole on the side. It was used along with the F carb. The parts number looks to be the same. If you look real close at the 2ed photo down you can just see part of the "F".
