Ikuyo Kamiya - Appassionata RCA 45 RPM LP question

There are two different possible RCA LP numbers for this TAS listed piano classic:


I'm wondering if anyone out there knows what the distinction between the two is?
is one 33 and one 45?
Sorry for the delayed reply - I've been a bit distracted. They're both 45 rpm, so that's not it - and I've searched the web exhaustively for any clues to no avail.
