Jumping in with Both Feet.
My opinion is that the red scale is a factory issued model with pocket wear and scratches. The 313 has had the scale altered in some way (so called buffed) which is shown by the rounding of the nail nic slot, even to a oblong appearance on one end. The black 307 was never issued with a smooth scale*, it is a substantial knife and could have been smoothed without rounding the shield by a careful use of a Dremel or even sandpaper. After Camillus closed parts were auctioned and 307s were assembled from various sources. Most that I saw were sawcut and I still credit them as true Cami 307s. Most sawcut shield 307's were flat sided on the scale with sharper edges than the one shown.
All that said there are two discussions here; one on what is the definition of a 'oddball' model. Do you considered only factory work to produce a odd structure as the only valid knife as a collector model or second are we considering personal touches that someone adds to a knife to cause it fall into this category also.
I have become a 'lumper' and less of a 'splitter'. To claim a knife in a collection as a factory mistake or (oddball) the oddball must have factors that are caused by the factory or the assembly of the knife at the factory with parts, printing, engraving or materials that give it odd character. Any knife that is different in shape, grinds or materials can be altered by a owner. I have on several occasions replaced scale materials on 303's. The occurrence of odd nics or liners from Camillus crafted 300s I have come to favor as a individuals choice, to believe them to be materials provided* at the factory to a culter as variations of that model era. I have published lists that gave a extra model variation because of a reverse nail nic vs. no nail nic. I have kept them on my list as different but will not argue with anyone who says that they are just different 'parts-of-the-day' knives and not true models.
In the end all these knives shown are odd-balls in the sense they are not like most factory issues. I have several of these different knives myself that were altered in someway, likely by an individual and I will call them odd-balls but they are not factory made slip-ups. If your searching for factory mistakes to collect be careful.

Here's a neat little odd-ball. It looks factory but isn't, might be a old custom shop but I doubt it. Someone did a excellent job in faking a jigged bone scale. Notice the main blade pin doesn't look right.
This is not factory...
This one is odd because someone removed the second blade. But, it fits in a strong sock well.
Now this is a factory mistake, Camillus factory that is.
Sorry, double post!
