Thanks for all the replies, makes me feel slightly better for myself that I'm not the only one. But equally annoyed that there are many more people awaiting film/glass.
I've emailed every address he has listed, PMed on here and other forums he is known to frequent with no reply. Luckily I did receive my Lumigrid Groundglass I ordered at the same time as my film, although in all honesty it was not brilliant. Wasn't noticeably brighter than the original Graflex one when it should have been - at least 2 stops apparently.
I wonder if Geert is still taking new orders at the moment?
