Just this one number - 7132, the same as the catalog number on the label - is visible in the runout area. The number 7131 is visible in the same area on the back.
By the way, I took a listen to the record on my Victrola, and was quite pleased with the music on it. I do believe it is electrically recorded. The flute solo is very quiet and peaceful (quite relaxing), but it can be heard over the minimal surface noise, and the violin solo is definitely not my favorite, but it plays loud and clear (also, both songs feature piano accompaniment). Regardless of rarity or value, this was a fantastic find!
