eBay sellers that do this are a pain. They are too %(*^ lazy to take pictures of the actual product. Instead, they take one photo of "a" paint chip set which they may use on 20 or more auctions of paint chip sets and then tell you:
"THE "ACME" PRODUCTS PAINT CHIPS COLOR CHART IN THE AUCTION PICTURE IS REPRESENTATIVE OF THE PAINT CHIPS COLOR CHART BEING OFFERED IN THIS AUCTION."
and
"THE ORIGINAL "ACME" PRODUCTS PAINT CHIPS COLOR CHART YOU RECEIVE WILL BE THE CORRECT CHART FOR THE YEAR, MAKE AND MODEL THAT YOU BID ON."
In other words, you have to take their word for it that they really have the right set for your car and that it contains the chips you are looking for. Unless of course they will accurately answer questions instead of flipping you off with "read the listing" comments. Keep in mind that this sort of "before sale" attitude will probably be reflective of the kind of service you'll get if you buy the set and it does NOT have the chip on it that you want.
My attitude on listings like this - even though I'm in Canada - is "I'm from Missouri. You'll have to show me".
Send back a similarly worded response that you aren't bidding on anything unless you see a picture of the actual item you want to bid on. Not a "representative" image. Don't expect a reply though. He's got over 2,800 items up right now and most of them are paint chips and lube charts. He won't have the time to research your question.
There are lots of different paint sets and lots of different manufacturers. In another spot, "Pete" has another listing for 1949 Kaiser DuPont paint chip set that has 35 paint chips on it. So, if DuPont had 35 chips in 1949, and "Acme" only had 24, it stands to reason the Acme set is missing at least 11 colours. Because even the DuPont set might not be complete. (So your question was completely valid and didn't deserve the kind of response you got.)
If you're willing to take a chance on this guy, then look at item 130315762117. It's the 35 chip DuPont set and you'll stand a better chance of your colour being on it.
Also, I have the DuPont chip set for 1954. Don't expect mixing information on these sets so you can go to a paint shop and have paint mixed. The chip cards (the ones I've seen) don't contain much more than the chip, the manufacturers colour number for it, and possibly the chip card makers paint type. (Dulux in my case.)
