DAVIES CHARLTON Engine Nos and Dating. Many thanks to: Martin, Robin and Engine Doctor for your interest and info given regarding my little DC Merlin. In my head as i said in my original post i bought it in the 60's pretty sure it would have been 60 / 65. The cylinder fins are very finely turned and the casting is smooth, fitting in with the Engine Doctors description of the early 60's Merlin. Thanks again to you all. If i can figure out how to post a photo on the forum 🤔i will do so soon. Best Regards Bryan.
