Could be, not sure, but I believe some of the class did pay off at Chatham for razor blades. What I am interested in is the colour paddler photo, as it reminds me of the Forth. I know they had the Swarthy there for some time, wondered if they are shufffling the grey funnel around to Inverkiething for razors. I am interested as I have for some time tried to find the port colours for the bulwark in PAS times.
