Since Daniel was unable to help (though he makes great decals) I will tell you that I got the one pictured above from FS Decals, http://stores.ebay.com/FS-Decals-and-Graphics , If you don't see what you need send him an email and he is quite willing to customize to your desires just as he did the fake Allis Chalmers build tag with the Simplicity numbers and my serial number.

Dare I jump in here? Sure...why not.....First the flatter fenders. I'm assuming it's still a three piece seat pan. If the arm rests are missing from the seat then the fenders often become fatigued from owners leaning on them etc. If your tractor has a round hood, similar decals and over all looks to have the same styling then it's either an early B-10 (1964) a BIG TEN (1965) a Bumble B-10 (1966-67) or a Bumble B-12 (1966-67). And as far as the ID tags....There's a guy that sells on eBay who can make you ANYTHING you need. I recently got a complete set from him for two of my 1964 Landlords. Also, Wellsimplement.com has complete decal sets that include the ID tag. Pierce2160 is the eBay decal seller. His name is Corey Foerster and he's awesome and fast!
Silk screening can make the placard. The original numbers could be stamped in by hand. Truth told the badge would be as original the numbers would be accurate. Painted or etched numbers are possible. Cricut http://www.cricut.com/shopping/ can make vinyl positives and negatives. I'm not an owner but i did see the videos. It is a cool tool. Etching or stamping the numbers is better than painting them.
