I just got a message from Keith Canham:

Larry;
In an effort to keep you up to date on the 5x7 TMAX 400 co-op, I am sending out this email. At this time I have interest in 55 boxes. I need 80 boxes to place the order. It seems that interest at this time has slowed. I have not had any new interest expressed in this co-op in about two or three weeks. If you know anybody that might me interested in 5x7 TMAX 400, please share the information about this co-op. I do want to thank you for your willingness to be involved in the co-op.
Regards;
Keith Canham
Hopefully some of you 5x7 shooters out there missed this thread the first time around. Get your orders in and maybe we can get a batch of this made for us.
