No identifying model name or number...judging from the bell size this may be an early "symphonic" model, simply identified by the "LM" designation. Beautiful restoration and a great price.

LM probably indicates a bore size of 495/509 (dual bore), the same as a recording

LM's (along with M's) were general-purpose horns; typically .495"/.510". Symphony-bore horns were marked "SYM".

As for model, it looks like a Self-Balancing. Can't tell for sure from the pics, but I think the inners are the original fluted pattern rather than the more common duo-octagonal.
