Unknown NOS parts

[remresto]

We have a pair of NOS Buick parts that were on our shelf. We were wondering if someone knows what they are for. Each piece has a small Buick logo, and one has the number J5973 in the cast brass portion.

Dear remresto:

The items are Buick dealer service tools. J indicates a tool usually made by a company named Hinckley-Myers. I can't help you beyond that.

Here is another picture of the other side of the parts.

Steering gear half nuts. These are pre 1928 and have less threads than the 1928 steering box. Part numbers for 28 are

256360 Half nut, assembly, right, includes half nut, thrust block and dowel pin

259361 Half nut, assembly, left, includes half nut, thrust block and dowel pin.

My parts books don't go back far enough, later steering boxes ( up to 1929 ) used half nuts with 5 threads, this one has 4 and the part number 15973? inicates it's from a pretty early model, possibly 4 cylinder?

I looked up the part numbers in the parts book for my 1915 C-36 and it has similer looking pieces but different part numbers. The book stated that these were only sold in pairs.

These look like the ones in my 1913 modle 31 Buick! I really don't want to take my steering box apart to verify, but they sure look to be the same.

The first time I reassembled the steering box, I put them in backwards....The wheels went left when I tried to turn right....Could be a fun prank on tour....
