ahh cheers, the quote block above is pretty much all i wanted to know :P as i know of the later track (the wider type you have in the photos supplied) being produced around the early 2000s as i saw it a lot in toysrus :P and ive got my head around the variations of the models of thomas produced in roughly the right order, brain just decided to send me on a spiral the other day becauseof the roof lever and that dream i had :P from what i'm gathering is my first clockwork set, despite having china track could well have been old thomas model stock? as i know when they produce models and toys and such they do tend to overproduce by a certain margin should replacements need sending out and what have you, so i could have had one of the held back ones, as i rebought the exact same set i remember having a few years ago and its the out the window lever, and even though i was happy to have the set again i always thought something was off yaknow?anyhoo, i'll leave the rambling here as i need sleep :P but i know one thing, i'm sorely tempted to have a go at 3D printing the rarest clockwork piece of all (purely for the challenge and usefulness of it) the playtrains diamond crossing, as i bought an ebay listing of a thomas and percy set (the beginning of this madness) because of said track piece :P never even knew it existed.CheersMr. Morris
