Dear Rav Kornfeld,
I've been asked by a few people (and I don't know the answer) to identify the author of Seder Vehilchos Karban Pesach Rishon B'ketzara which is in the introduction to the Fifth Perek of Maseches Pesachim, Perek Tamid Nishchat.
If you can identify the author, kindly email.
Thanks
I do not know the identity of the author, and no one whom I asked knows either. However, it is clear that the Halachos that are written in that summary come directly from the Rambam (although not in his wording, or in direct order of the PErakim), with a few minor additions from other Rishonim in parentheses.
