||Op.3, No.1 and No. 2 are sets of variations identical to Op.2, No.1 and No.2
Based on multiple old scores I've come across, it appears that both Op.3, No.1 and Op.3, No.2 are identical to Op.2, No.1 and Op.2, No.2 even though they are labelled in a way that could easily be understood as them being different on various lists of Hummel's works.
