LocoWorks - GVT Loco (2) - wheels !

 I had a spare LGB Otto 0-4-0 chassis, which is just suitable; valve gear and rods removed...

and some extra bits cut off to fit it under the loco...

Increased the length of the slot in the bottom of the loco to accommodate the chassis....

The chassis positioned - nice fit and room for the running weight inside the loco's boiler

about 8mm of wheel and con-rod show, when the chassis is in place - not that visible when it will be running (the con-rods could come off if necessary)
