My client has a 1923 Buick, he wants keys for the transmission lock located on the floor at the base of the stick shift
there is a letter 'B' inside a diamond which I suppose is the manufacturer and a number 'B342' on the face of the cylinder
Also the ignition lock made by Yale, I was unable to find a key to fit it, looks like a Y-1 profile but smaller in size--
Anyone have any ideas?

Also he has a 1929 Willys Overland, I wish I knew which keys fit it, I did manage to make a key for his 1932 Chevy,
using a B-10 blank, it has a pop-out ignition, first I have seen
