Help needed on how to sew Gauntlet & Braemer Cuffs

[betsybug]

Hi all
I am in the midst of learning how to draught and sew a bespoke jacket. The first one I'm making right now is with normal cuffs (working buttonholes). For my next project, I would like to tackle an Argyll jacket that I can use for piping events. My question is this: how do you draught a Gauntlet style cuff, and also how to sew on a Braemer one (the latter - it looks pretty straightforward from photos, but is there a proper way of doing it)?

Thanks for any help.
