For me the line bounding my main area of interest includes the regular wheel era but also includes super fast castings which originally had regular wheels. Think of it as another wheel type: MW, GPW, SPW, BPW & SFmatchbox_n_molars wrote:My Matchbox knowledge has a very clean cut at the termination of the regular wheel era.
Then I also add in realistic SF castings like the Europa and the Marzal.
Those are my areas of interest...my area of knowledge is much, much smaller. In fact, I'm still looking for it!
