I am assuming this is the truck we are discussing? - http://cgi.ebay.com/ebaymotors/RARE-ORAN...=item2a31e80bb9

If so I can say this much the exhaust stacks are not original
"Lil Red" stacks. I do not believe those wheels came out until a few years later also.

The VIN checks out as a Warren Built 440 Utiline though and that makes it pretty rare anyway you look at it.

I believe the 1 of 74 is based on the old Galen Govier letter from years past which has beeen disputed by many. I believe you will find the wording is something like it is "1 of 74 that have been documented" and since he is the only documenting them that just means he has seen 74 so far.

I have also seen the same letter that says 1 of 78.
