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.
