I have followed on the forum and some have talked about OC-5 and OC-15
I have never seen those crawlers and it
would be great to see some pictures of them , i think itÃ,´s more than me that would be intrested.
I have a stack of slides of the OC-5 that I will post to the Album as soon as I can get someone to scan them. This model was never produced commericially.
The OC-15 is a very common tractor. I don't know if I have any pictures of it though.
