The frames for the air filters at the radiators end of 50030 were corroded, warped and generally unusable after 25 years or more out of traffic. Although we had a number of spares they likewise were not much good having been stored out in the open or in damp environments. We decided to "bite the bullet" and place an order with an engineering firm to have some new ones made. Ian Kemp went along today to have a look and we are vey pleased with the results. Coincidentally the firm's proprietor told us that his father had served on HMS Repulse (the Resolution class nuclear submarine) as part of a 25 year naval career.
