What you may have wanted was a Crail or Braemer Jacket. Typically those are less ornamental than an Argyle.




I'd gamble that the cuff is surface applied over the sleeve so there should be a full sleeve under there. What I'd be afraid of though is that if the jacket is old enough to show signs of wear, the visible sleeve may have faded and removing the cuff will only show the darker original color of the jacket

Does the jacket have shiny buttons on the cuffs? If so, you might could sub-due the appearance a bit by replacing them with bone, wood, or horn buttons that are brown or black.
