I have a soft spot for “the” branded things. Buescher at some point thought that this mouthpiece was the one that epitomized their brand. Scooped sidewalls, large round chamber, no baffle. Tip opening measures 0.068″. Classic swing era dark tone. high resistance, low to moderate projection. This would look great on your Aristocrat.
