I was delighted to find and purchase this one this week. I believe it is an Academy Award "L".
The case is 14k yellow gold. It has unique lugs and is a very petite watch like the "M" and "KK". The case and movement are date stamped L1. The dial is in pretty nice shape and the movement is working. The crystal was very scratch so I had a new crystal installed and I installed a NOS band.
