Moving the valves out of the roof space and into proper storage boxes gives me a chance to re-do the pictures of some of the older exhibits. So, CV378, CV430, CV1934 and CV5008 have had a makeover. Also, the CX1140 was destined to be removed but I can see a faint CV marking on that concurs with what it should be. So it’s been renamed CV8563 and tidied up. The CV number is written on the base in ink but I had not looked over it carefully to see if there was a trace of the actual mark, and there is.
