http://www.sakainet.co.jp/japanese/playland/index.html The above link has several reasonably detailed models of compactors (the type used in building roads). Not sure if this is known about or not, but I like them. This page can also be found in english, but it doesn't have as many models.:cry: Also on the website are text instructions, with a few detail pictures. (First link below the model pix on each page.) Have fun.
