Yes, after you use it a bit you pretty quickly get used to where the Alpha symbols are located, or at least the symbols you use often, such as ?, =, <, >, etc.

Here is a post from a long-time member that sells overlays for the 41C:

Blank overlays were not listed when the post was made, however it's possible that they are available as well. Contact Michael via PM; he's in Germany, very helpful and quickly replies.
