The “L” could be the action (light). Ending in “ell” could be Mitchell?
No, the first letter is definitely not a “M”. A Mitchell would be cool to have tho’, even though I’m not really a collector.
The “L” is in large cursive, and I’m pretty sure it is definitely part of some sort of company or series name. The other lettering / numbering is in a smaller, simple font, similar to Arial Bold.
