Branches of the Menorah - Curved or Straight

<p>Were the branches of the menorah straight or curved? If you ask your average person (try it) you will generally recieve the response: It's a machlokes Rishonim. If you ask a more academic leaning person, the answer may be 'it was definitely rounded, haven't you seen the arch?'. <span style='color: rgba(0,0,0,0.65);background-color: rgb(255,255,255);font-size: 14px;'>However, the Lubavitcher Rebbe was adament that it was in fact straight.
