While looking for something else tonight on our favorite Japanese model railway website, I came across this.
While I can't vouch for the dimensions, it does have spoked wheels. The price appears to be about NZ$130 (at todays 67 yen to the dollar).
No I'm not buying one, as I have just looked at all the 1/2 finished loco projects on my workbench
(and I keep spending money on brewing supplies)
