John Deere Van Brunt fertilzer spreader ID

[Frank Sterzen]

I picked up a JD Van Brunt fertiler spreader but cannot find a model number on it. It's 8 feet wide with two bins. There are disk type mechanisms in the bottom of the boxes. There is also a box of drop tubes with it. The previous owner bought it on an auction but never used it and has no manual. Any ideas what model this may be and where I could get a manual?

Wood or metal boxes? Also, wood or metal wheels? How many drops are there?

I have a couple old manuals could probably ID it, but a pic would be best for everyone on here.

I'll guess from the description with no photo model LF if rubber tired or MLF if a 3pt model

Thanbks. I don't have a photo and the unti is a couple hundred miles from here. It has metal boxes and rubber tires. On the right right it T-144 written in yellow.
