Hi, I recently obtained my very first pre 1950's car. I have a 1924 Dodge Brothers Touring car and according to the family, the motor was taken out and restored in 2000. They drove the car for a while and then put in storage. Early last year, they had to get the car from the storage place. It was then stored outside, under a tarp. I bought the car a few weeks ago. It is basically high 90's% original. When I bought the car, the carburetor and vacuum tank canister for the gas was missing and the horn and the wooden steering wheel. I bought a couple of carbs and a couple of tanks and horn and metal frame of steering wheel all off of ebay. I had also purchased a potpourri of books to learn of the car and how it works. I took the ignition lock out of the dash, and took it to the local locksmith to make a key. This car has a transmission lock on it and I need advise to how to remove the lock to have a key made for that as well. It is a Yale lock, cover. Any advise to help remove it from the transmission housing ,would be great. I also have an issue with trying to decide if this car is positive ground( I think it is) or negative ground. A battery cable is on top of generator, the other battery cable is attached to the transmission tail housing/support. This car is also equipped with what I believe is an oil filter canister mounted on the right side of motor, just above to the right of distributor. I have not seen any like this set up in any of the pictures and images that I see on the computer. I assume it is an oil filter, one bolt on top, once cover is off, there is a little wire handle that you use to pull up and out of the canister, so I assume this is the oil filter. The odd thing is, there is not any oil or residue of oil anywhere inside the filter or canister. But the car had sat in storage for almost 20 years, so maybe??????the oil simply drained into the motor??? My other observation of this canister, is it is plumbed with copper piping and one of the tubes is attached to the oil pressure guage in the dashboard. I know I have a lot of questions mixed within my new member intro, but any help with images, or opinions, or suggestions would be greatly appreciated. I always wanted an older car, like a model t type car or Duesenburg ( really out of my price range)so this has become my new adventure. Thank you.
