Wiard 2-12 3pt plow info wanted

[lhfarm]

I picked up this plow last fall with the hope of using it as a display plow on my 1949 farm jeep. The jeep was rated for a 2-12 and I'd really like to find a Newgren brand. This Wiard has the forged name on frame (marked B1 and B2), but no other markings I can see.

I've done some research but haven't found anything that might help be date the plow. Anyone have any ideas about when the plow might have been made or if I need to look for other marks?

Thanks,
