Today I had a problem with my nearly 30 year old Wista DX. I was at 14,000 feet on Mt. Evans in Colorado and it suddenly turned quite cold. In fact it started to snow. My Wista focusing rack suddenly just seemed to freeze up. The focusing rails on the bed are wood against wood and they have at times been stiff. Is there any way to lubricate these rails. I finally got it working and cleaned the rails but I'm afraid this problem might return. Does anyone have any experience or ideas about this.
