I have seen two odd radiator fill necks on T radiators. Both necks were on 1926 flat tube, two row core radiators (the odd balls), Unlike the familiar plated neck used on most low and high radiators from 1917 to 1927, these necks are perfectly straight with internal threads for the cap on the inside, kind of like 28-29 radiator fill necks. Has anyone else run across these type of necks? I can post pictures, later.

I have seen them on made in China aluminum hot rodder radiators.

I can see that on them, but these were two original brass radiators with no manufacturer markings except for a series of embossed numbers (serial numbers?). They, also, both had cast iron upper tank inlets that were rivited to the upper tank, kind of like the upper tank fitting that Berg's uses on his reproduction radiators, except Berg's inlet fittings are cast brass.

On the first T I purchased, it had an aftermarket radiator with no hole in the top tank under the filler neck. It had a pressure cap on the inside under the hood. It used to blow out the freeze plugs, so I drilled holes in the top tank under the filler neck and used it without pressure. It worked fine. Later I got a brassworks radiator.

A lot of era and post era after-market radiator cores had straight fill necks on them. Perhaps this is an aftermarket two-row radiator?
I have only looked closely at a couple original two-row 1926ish radiators over the years. I never did much with the improved model T myself, so I never looked closely at many of those radiators. However, the couple I did look at closely had the usual Ford radiator neck.

For whatever all that is worth.

This is the radiator I put on my '22 Coupe. The neck is the same diameter all the way to the tank. It is a low one and one of the aftermarket replacements. Some may recognize the neck casting. I would replace it with one with the proper neck but it cools better than any others I have. It is tube and fin but I have some cellular radiators with similar necks.

Rich, the radiator that I have, and the other one that I've seen, both have a straight neck like the one that you pictured, so maybe mine is an aftermarket. I just assumed since it was a two row flat or oval tube, that it was one of the rare 26 radiators. The neck is crimped to the top tank. I can't tell if it is also soldered. If it is, its a darn neat and nice soldering job.
