Are the double tube brass tire pumps for the early Model T's hard to come by? Also, what would be a fair price for one?

Based,on what I've seen at swap meets and auctions, I'd say they're not plentiful. I have no idea about prices. I'd check ebay and see if any are there, and watch what they bring.

Triple tube pumps are even harder to come by but sure look neat.

The double tube pumps that were used on the early Fords were made by the Bridgeport Brass company. They usually have the remnants of red paint on the bottom cast iron base, and say the Bridgeport name on them.
I have bought two of them. One was about 16.00 and the other was about 30.00

Bridgeport also made a three stage.

O.k. this may be a dumb question but what is the difference between a single pump and a double tire pump, besides the obvious! Is one better than the other? I've seen other brass tire pumps with only one cylinder so why the double?

Why does one triple pump have the small cylinder on the left, while the other has it on the right?

The Kellog is for the front tire. The Bridgepot is for the rear. It's in the Darn Book.

I believe one is facing forward and the other is facing backwards - according to the air outlet nipple I can see.

I have no idea but I suspect that the different tubes work together to fill the tire as quickly as possible: the big tube flows a lot of air at lower pressures, but as the pressure increases you need the smaller tubes generating more PSI to help stuff more air in the tire. If you only had the one large tube you would push the handle down a long ways and all it would do is compress the air in the tube, not push it into the tire. Just a guess though.

"Each cylinder is in series. The large one supplies the middle one which supplies the small one. The compression is more efficient that way, just like a compound steam engine. It should take less effort to pump up a tire, especially to high pressure."

You would think that three tubes would be harder to pump but some of the compressed air is helping you on the back stroke. the air is much higher pressure coming out of the small cylinder than on a single tire pump.

That's my theory.

OK it's Bridgeport and not in the darn book.

To try to get 45 lbs in a model T tire with a single cylinder pump is very difficult. Most cars today are 30 - 32 lbs which is relatively easy to attain with a single barrel pump. The three stage pump would make 45 lbs very easy. I have a single stage brass pump with Ford cast in the foot hold down payed about $60. Does any one know if the is model was supplied by Ford or is it after market/jobber.
