Showing off my collection!

Molly uses a flat type drive unit which was included in murdoch, emily, as well as engines like oliver, donald and douglas, spencer, bill and ben, rheneas, maybe skarloey, sir handle, peter sam or rusty and maybe most of the later fisher price engines (don't quote me on that because i don't own the latter engines) so it shouldn't be hard to find a replacement motor or cog
