Hi. I can try to find it, but, to be completely honest, the odds of finding the pattern are almost impossible. Well...it would have possibly at one point, but those records are long gone. If you'll notice on replacements, of the Lanternier patterns are basically just modern numbers. That means there is no official name for the patterns. Replacements has one of the best current databases. If you don't find a match there, you probably won't find one anywhere else. There is no official book or catalog to look through.
Did you just go through their database or did you send in a pattern request to them? http://patternid.replacements.com/ If you sign up with that, they will actually email you when/if new pieces come in.
If you want to send a picture, I'll be more than happy to try. I just want to make sure you know I can't guarantee finding the name.
