I think virtually all school library's had the two bound copies of this magazine. They were a life saver on wet days when we were prevented from playing, if that's the right word, outside.
I have the two bound volumes plus one spare as well as a complete set of loose copies with their cover's. I thought that these had been stolen but, one of the lads who was clearing out my attic the other week found them again and was on the verge of throwing them into the skip until I glanced over to him. He's still alive and helping demolish and rebuild my gable as I write this.
PS. I also found a complete set of bound copies of Railway Wonders of the World. And well worth the £35 I paid for them in Hay.
