I think you may end up spending more for the decal Vm than what the Rover Baron is worth ,I must have scrapped about 40 Rovers recently ,all with good alloy bases and a few Baron mowers ,I paid $5 each for them and advertised them at $5. just to move them on but no takers so scrapped the bases.
There are a lot of old Rovers missing the catchers and that kind of makes them worthless ,I had one Barron that was slightly modified to fit a Victa Sports thumb latch catcher.
