There are some interesting pencil marks still on the wood inside, like where it was marked to cut at a specific angle, and there is a symbol under the cover for the keys that looks similar to a Christian Fish symbol, but looks like, from where it's layed, it would've had to have been marked prior to installing the cover, which I found interesting and have included a picture of with this submission.
This was purchased around the early to mid 40's for my Mom, from what I recall her telling me when I was young in the 70's and started taking lessons.
