I see considerable correspondence in the past regarding the RAF 43ft RSL. I built one about 10 years ago at 1:8.6 scale, ie., 60 inches in length. I built it in entirely in aluminium (the real one had the superstructure in aluminium) and it remained 80% finished until recently. I see in the correspondence (I'm new to Model Mayhem) there is reference to AP4554 Vol 1 and Marine Craft Directory Appendix B which probably will contain the extra detail I need to finish my model. I have tried every internet lead to locate a copy of either, including many so-called sources to no avail. None of them answer their 'message us' page and specific people with this information do not reply to e-mails. Does anyone out there still have either of these documents who could either sell, or e-mail me scannned copies? I would specifically like any info on number 1663 (1663E) which is the least photographed, only 2 pictures, and was lost in 1959. It is the one I am modelling. Many thanks, Peter.
