The challenges of judging aka Manufacturer logos C1

[Mike E.]

"But my car has...." is a mantra I've heard probably a thousand times since joining NCRS in 1974. I know that GM generally had multiple suppliers of smaller items like bolts, etc. I also understand the assembly line process. I have a deep affection for bowtie cars that are text books of what GM did. I have several photos attached that help underscore the challenge of sorting out real cars from made cars.
The first picture is of four brass brake blocks at the master cylinder. All are take from different 62's. All are weatherhead logos, but check the difference.

The next photos are of the bolt that goes into the brake block in the front of the master cylinder. All the 62's I have ever really looked at have the small dot as the logo. However, I'm working on a 57 that has a different logo on that bolt.

The final photo is of the three bolts holding the original small 022 master cylinder to the 57 firewall. All three have logos that GM used regularly on the line. The 56-57 JG spells out the WB1C. Whoever grabbed them out of the bin didn't check them for head patterns and coordinate them.

It's always interesting 50+ years later, isn't it?

Mike,

The 56-7 JM bolt & screw charts represents 40 plus years of the collecting information on bolts & screws "normally" found in original/unrestored 1956 and 1957 Corvettes with input from Mike Hunt during the 80's.

As you point out, there's always an exception. And no they didn't stop the line because they ran out of a particular bolt head mark.

1982 (IIRC the exact year) Bloomington I spoke with someone who had been in the St. Louis purchasing department. I don't recall his name. He told me at times when factory bolt supplies were getting low for a particular size bolt, buyers would purchase bolts locally in the St. Louis area.

Gary,
I knew Mike Hunt well. Spent time in his basement (unheated) in the winter in Madison. I have some of his research reports. Has anyone carried on his work?

Mike,

No one has continued with Mike Hunt's 1956-7 Research Project. Met Mike Hunt at Bloomington in like 1980 when were both looking at a 1957. Mike and my military background were somewhat similar, so we had two things in common. Would visit with Mike at Bloomington and I spoke 2 to 3 times a year until he "hung up" his research project in the 90's.

Had spoken to Mike in July and he was going get his diskettes out of his attic and send them to me.

All Mike's data and papers went to Kettering within 6 months after he died in the motorcyle accident in August. Kettering committed to setting up an exhibit of Mike's research project according to Ken Kayser. Don't know if that's been completed or not.

The variations of the items you pictured doesn't surprise me, at all. Features like these are much more likely to vary than they are likely to remain absolutely the same. Somehow, some folks have got the misconception that certain features, which really amount to nuances, have got to be only of one very specific configuration. In my opinion, that's absolutely ridiculous.

Great info Mike. Thanks for sharing.

I re-sealed side windows on a very original '62 recently, and found these logos on the sashes of both in remarkable condition. I had never seen them before. Here are some pics for your records if you want.....

p.s. The Mike Hunt data is so very interesting. He was a great contributor.

Rich,

Interesting logo XL. Thanks for sharing. Searched my 1963 Fastener logo and the XL logo is not listed.

The GM Engineering Standards books for that period would have that manufacturers logo listed. I've never been able to acquire a set of those books.

Gary, Yes I was quite surprised to see that one. If you ever get a copy of those books I'd love to see some examples.
