That would be greatly appreciated Chipper. I was surprised to read in Jon's thread about the cardboard tag. I have spend a great deal of time/effort on some minute details and this would be a great little thing if I can make something real close.
This is a photo of a reddish brown fiber tag. It is the same type of thin cardboard used in some of the gaskets. It is not flat but curled a bit so does not photo completely accurate and part of the edge of the hole is missing. One should note that it contains punch holes indicating passing quality inspection at various stages of assembly. It was attached to the carburetor and held in place at the choke shaft. Also note that it does not have Carter model number like the brass tags found on a number of RJH-08 and later W-1 carburetors.
Based on my research the brass tags were installed on factory rebuilt and later production carburetors. In most cases they have the Carter model number stamped in the tag in addition to a few inspection punches.
Somewhere, I have a new old stock one that does have the model number; but I haven't seen it in decades, and would not know even where to begin to look for it.
If it ever turns up, I will post it in my virtual carburetor museum, but don't hold your breath.
Chip - thanks for posting the picture of yours. Obviously, in a 100 years, the color has faded. Originally a medium to dark red in color.
I have not seen documentation where Carter switched from the cardboard tag to the brass ones. GUESSING 1932. I may have the documentation somewhere.
Jon, I am also of the opinion that about 1932 was the change from fiber to brass. Some of the brass ones (I have a bunch of them) have Carter model numbers and others the Chevrolet part number. I believe it was that beginning in 1932 there were two different carburetors that looked the same. Either car and truck or Master and Standard ('33) for example. The assembly line workers would need to know which to install on a given engine. That required the stock people, etc. to also know which was which. I highly suspect that those with the Chevrolet part number were made in the Bay City plant. I should have noted that when I took them apart but if I did I have now forgotten that detail.
One interesting difference is that some carburetors have the Chevrolet part number stamped on carburetor parts and others the Carter number. I am sure the Chevrolet numbered parts were made in the Bay City plant.
I agree that the color of the fiber tag pictured has been altered by contamination and age. I believe a oxblood color was the original. I think I have another one or two but didn't find any more when I looked.
