Manufacturers Mark ID

[Old Pueblo]

Can anybody tell me what the manufacturers mark on this bottle is? It looks like and "L M" in a circle, but I couldnt find anything on it when I looked here online. It says "4/5 Quart" around the bottom.

Here is a pretty decent bottle mark site: https://sha.org/bottle/pdffiles/LLogoTable.pdf

Thank you. I thought it might be Latchford-Marble, but I wasn't sure because the thing I was reading didn't have a description this particular mark. Thank you very much! I was really hoping to put a date on this.
