Went looking at a D2 today. He was interested in whether his D2 was worthy of reviving.  It is  3J 6388. The interesting thing about it is the loader attachment on it.  It is a Teale and Company,  Manufactured by Burg MFG inc.  
I was wondering if anyone had any info on Teale and Company or Burg MFG.  I think it must have made attachments for crawler tractors, Cat included, much like LaPlant Choate.
The tractor isnt much to look at. It has set outside in the yard for 25+ years. Pretty sure both motors are stuck and probably the tranny too. Other than the loader attachment and PTO, I dont think it is anything to special.  
When I get pictures downloaded from phone, I will post some.

My one and only piece of literature on the Teale loader for D2....
Would certainly be an orphan to find parts for but at one time it was probably a barnyard favorite.
