Which cars used the T-Type Jack " identification"
 

I had some jack shafts, bases, hoks ect.. replated. I have one left over, it is a T-Type shaft 34 1/2 inches long. The base has a large A and a smaller B stamped into it. Jacking mechanism has a 9A stamped on it, but no date on the rivets. I have some pics but are too large to download. Thanks.
