Pretty good condition with most of the original decal remaining, needs frequent pricking so a burner service due. It's got a different air release to the other Mk1s I've seen and a pump shaft that locks closed by turning when shut.
Hi norf, a nice example of a Veritas Mark 1. Yes it has a different to all the other standard arrangements. The filler cap is very similar to the Monitor filler cap with their patented built in pressure release but with the pressure release key in place of the SD.
