I have a black longbed Singer 301A that came in a case. While we were vacationing in Wisconsin we happened upon a tan shortbed 301A with a pretty battered up case. It was headed to the trash but we salvaged it. I have since got it sewing a very nice stitch. Since the case was pretty battered up my DH decided he could do a little repair work so he took my case from the black singer to use as a guide. While he had them sitting on the deep freeze in the garage together, I noticed that one was smaller than the other. Were there different sizes in these cases because I didn't think there was any difference in the size of the machines that were sold in these cases.
Here is a couple of pictures.

I’ve got a LBOW (two-tone) 301 shortbed in a case like yours that is about 12" high. My mocha longbed’s brown case is also 12” high but looks like faux alligator, and is probably not original to the machine.

You will get more responses to your question, if you ask the moderator to move your thread to the Vintage/Antique category. There are a lot of 301 threads there as well as some interesting links.
