Manufactured by "3D-to-Scale" (model #64-402-GY; the 3000toys.com web site no longer shows it), which is a private brand of the diecast retailer 3000toys.com. Their products are all 3D-printed. Most of the products are S-scale, but they also have some 1:50 scale items. The products are pretty much all geared toward farm modeling. I bought this tractor since I now model 1924. I actually wanted to buy another of 3000toys' products, and to justify the shipping cost, I added this model. This is actually my very first 3D-printed product. It arrives as you see it in the photo.
The biggest issue I have with this model is that I have no clue as to which prototype it is based on. One candidate is the Hart Parr tractor. Early Case tractors also seem to match it somewhat. Further research will need to be done.

The model measures 16' long, 7'9" wide, and 5'8" tall.
