I'm having a curious problem with Field Manual: Periphery:
My copy is titled "Classic BattleTech Field Manual Periphery, and is FanPro #10982.
However, the product list on Sarna as well as another, older product list I pulled from the internet once upon a time list it as FASA #1726.
I surmise that this was a book largely completed as a FASA project when FASA closed its doors, and the project was seamlessly taken over by FanPro (FanPro US being practically FASA with a new nameplate as far as the author and developer pool goes).
But was there ever a version of the book published under FASA's aegis, and the re-published by FanPro? Or was it only ever published by FanPro?
(Another, better known example is the MechWarrior 3rd Edition RPG which FanPro had to rename Classic BattleTech RPG for their reprints.)
