Hi SkinnyLinny, Nick and Chris
thanks for your posts. I'm not an experienced modeller or researcher or researcher so any help is much appreciated.
Thanks you for the .png Nick.
Chris, if you could send me a copy of the drawing you have I would be very appreciative. My address is Andrew McPherson, 5 Widgeon Way, Hayle, TR27 6GQ.
Once again, thank you all.
