.... and the leather does not appear to me to have the "red dots" which I thought it was supposed to have. It is much more uniform like it is bamboo instead of cognac. Can any one tell me if this looks right? Do I have bamboo?
Quite clear that you do not have an acceptable "cognac" leather. Most vendors will sell you what you received, some offer two types where one is a better approximation. For example, GAT has a #15 that looks like yours and a #18 that is better:

The price is almost double but IMO it is worth the extra cost.
The armrest on my 1964 230SL had split seams and the leather was so brittle that it could not be fixed. I sent the old leather to John and asked him to match it. That is when he informed about the new source and I must say it is an excellent match to the old leather on the door panel! It even has the yellow/tan color of the original on the back side and is nice and subtle.
He also sent me a sample of the "cognac" colored leather and as the photo demonstrates it also is an excellent match.
Unfortunately he has not had time yet to update his web site so you need to call him if you want this "oldtimer leather".
Wallace, if you read this, the sample is on its way to you!
