Some not in the list, some misidentified and some inconsistent moderation - especially where the vehicle was a joint venture or crosses eras. I've had a few where I've had the same photograph a couple of times, the "this photograph is in the process of identification" message has flashed up but then I've received two different and conflicting responses in notifications. (The same Little Willie photo identified as both WW1 and not WWI for instance, presumably be different moderators.)
A puzzle is what happens when there isn't an entry in the list - but you can select the donor or base vehicle. How do we respond to all the Kangaroo variants? Only one is listed. It seems odd to have to positively identify one specific variant, but then answer for the donor vehicle for all the others. Can you answer A12 for a Scorpion Flail, for instance? Technically it's correct.
If you can then, what's the point in differentiating between the M4 and the M4 Crab or A12 and A12 CDL within the drop-down list? Sticking a .50cal onto a Toyota Hilux doesn't stop it from being a Hilux.
