Well I suppose it has a hint of the Scraper plane about it. Apart from the different knob style, the side wings going further back on the scraper, different rear tote, different sole shape and, of course, the completely different blade and adjustment configuration.
Apart from that, heck, they're practically identical... :roll: :lol:
I think we may have confusion over bevel angles and effective pitches here, btw. As I understand it, ydb would favour having an iron with a 50 deg bevel angle for an effective pitch of 62 deg, while the BUS comes with an iron with a 38 deg bevel, giving an effective pitch of 50 deg. I think you'll have to resign yourself to having a wide range of blades from which to choose, ydb - specially as you're making space for the bevel up jointer as well, IIRC?
