the annoying thing is I don't need a working finder so even $45 seems like a lot for essentially just a cover. but I guess that might be my only option if Mamiya never made any covers. Unfortunately KEH not an option - they charge insane shipping prices to Nova Scotia. I once got them to charge me actual shipping (I think it was $50 or $60 LESS than their quote) after talking to a couple of different levels of supervisor but it's not worth the hassle.
Judique I think is in Cape Breton - I may have driven through it a couple of times
You're right, Cape Beton, mea culpa. Ann and I arrived in Nova Scotia simultaneously with hurricane Earl, so we weren't always sure just where we were.
You're also right on the shipping, that's some ugly shipping fees to some place on the same continent.
I've been using RBs since the mid-seventies and am not aware of any cover for the focusing screen other than the WLF.
I don't know any of the big city camera shops up there in the north woods other than Henry's, but surely, there must be a KEH-ish store up there somewhere.
Maybe someone in Baja Canada could "trans-ship" one as a "gift" to you. Wink, wink, nudge, nudge!
When I had my studio I was the king of foam core, you can make almost anything from foam core and gaffer's tape. I made several 4x5 (5x4?) focusing screen protectors out of it. The stuff will compress if you apply enough pressure so it becomes a "crumple zone" for your ground glass. Very effective.
