Drumohr sweaters were well thought of on here about fifteen years ago. At least as good - possibly better - than McGeorge.
I became slightly acquainted with Zegna once at an Italian airport. It looked fairly expensive.
Wasn't Drumohr taken over by Italians?
Possibly, I remember reading The Weejuns blog, when he went to De Paz of Bologna and picked up quite a few NOS Drumohr.
The wonderful world of Ebay: someone had a Drumohr/Zegna sweater on with a starting bid of £25. It didn't sell and is now back on with a starting bid of £55.
