The model # and size is printed inside the boot, but it probably wore off due to use.
I don't think they're Medallions, definitely not the Gold Medallion, which was the top boot in that series.
I think (although I could be wrong) that the Gold Star was sold boot-only, so I wouldn't expect someone to mount a stock blade. You'd probably see a MK Pro or JW Cor Ace instead.
The Wilson Excel was sold as stock blade with the Riedell Bronze or Silver Star set.
I'd guess it was a Bronze or Silver Star boot.
