Ah, such memories, Sandy. This Merit kit was my first ever rigged (with HSP) model back in early 1970s. I wasn't advanced enough (and always in such a hurry to finish a model) to sand down the raised markings. I did paint them in, though. Humbrol paints were all we had back then. At that time, as a lad of around 14 or 15 I thought it was the pinnacle of modelling prowess.
I also bought the Harry Woodman book and still have (and treasure) it.
Cheers
Syd
