Dozer blade information wanted

[430c/440ic]

I am looking for information on a "Holt" made dozer blade on my 430c. It is a 7-1/2' outside mount with manual angle. I have only seen one pic online of another just like it. If anyone has any information about it (model # or years of production) or even more pics like it, it would be greatly appreciated. Thanks in advance.

Wow I started this post 5 years ago! I also came across that web-site and emailed them, Mr Leonard was very kind and informative on the Holt blade. He had met Francis Holt many years back and he shared some original literature and drawings with me. I haven't found any more literature but what he sent me.
