Terri's favourite

This is Terri's favourite teapot...
It's a Homer Laughlin (maker of Fiesta) Oven Serve teapot in Pumpkin glaze, circa @1935
It is very rare, in fact he has yet to find a single person who claims to have another like it! One book reports the OS teapot as "reported, not confirmed", and another lists as extremely rare. No one seems to know if they were in regular production or whether the few found are prototypes.
If anyone has any more info on this teapot let me know.
