Well,the 8160 is one of a kind.
If somebody asked me to pick the one that would get the most looks at a show and would likely be the only one in the US,I'd probably have to pick the SAME built 462.
Even knowing what it is,I always thought the G1355 was the toughest looking Oliver ever. The 1865 is a rare bird that looks tough and would be on my list too,along with the 2655.
I wish I could find the 500 that the neighbor bought new back in the early 60s. I know where it got traded in on a new Ford,but nobody seems to remember where it went. A 600 would be even more rare than that.
