Staybrite Shutters. ------------------ Further to our note BY5/G.6.10.30, we are handing to you herewith the three shutters which have been descaled by the acid etching process referred to in our note. We shall be glad if you will have these shutters tried in order to see whether any grease or dirt can be removed by merely wiping as the suppliers of the material stated. If this descaling process fails to meet your requirements for a matt finish on these parts, we have nothing further to put forward. BY/EM. | ||
