I was visiting a friend of mine yesterday and in his stash I was surprised -- no -- amazed to see he had not one, but TWO early brass gas caps.

I looked for years before I found one for my 1911.

The thing that is interesting is one has an open bottom, the other has a baffle on the bottom. I have never seen one of these with a baffle on the bottom before. Mine does not have a baffle...

Comments?

keith

the one on my 1911, which is believed to be original to the car, does not have a baffle, nor the appearance of ever having had one. cheers

My 11 has the open bottom cap, I believe it's the original cap.

Ditto on my 1911. Open.

My guess is that someone added the baffle to reduce the amount of gasoline splashed out the vent hole when the tank was full and the car in motion over rough roads.

Not a bad idea, but I doubt that Ford would have spent the time or money to install the baffle as it wasn't critical to the car's performance.

The photo of the tops of the cap are not showing here. From the bottom photo, the one on the right looks like a '25-7 cap.

The photo finally came through. You have the correct caps. Not easy to find.

Keith, I could use one of those caps on my '10 - are you willing to part with one???

This is the first early one I have seen. That's one more treat the forum has had for me.
Ford did have baffles like that on later caps. Most of them are missing:

Vendors sell a baffled version for those who want them.

All three I have do not have a baffle.

Richard, would you be willing to part with one???

Here is the underside of mine:



No Baffle.

Bill, the previously pictured caps are not mine. If my friend is interested in selling, I'm sure he will contact you.

Keith, here are 3 originals from #314, 4013 and 23,805. I go along with Tim, I think the baffle was added.

The one (NOS) with the baffle came out of Otis Clinton's traveling swap-meet sewing case - some of you guys might remember it - I believe he always had it at the Harrah's meet.

In the encyclopedia, Trent has some information about gas caps beginning October 10, 1911. The material was changed from brass to malleable iron.

Two weeks later on October 24, 1911 the material was changed again, this time to cast iron with the specification that the cap be tinned.

On February 3, 1912 the material changed again. This time from cast iron to aluminum. Same design, just a different material.

It goes on with the style unchanged for several years, which sounds like all of these are like the cap on the right.



So maybe the brass cap on the left was "discontinued" before October, 1911. Of course a record of change doesn't mean it happened on the assembly line on that date.

Thanks for sharing your day with me Steve.

This cap is brass, believed original to the car.
