Agree, the V5 entry needs an update. Also noticed on our V5 what looks like an EPM on the female part of the clasp. Lots of differences between the male parts of the other clasps too.
Re: Heath's belt - it does look mostly like our current V5. I've highlighted the pic for a couple of observations:
See the raised 'dot' on the belt strap near the pin. What is this? Unfortunately we can't compare this to our current V5 as the belt on our pic is not fully open.
See the 'sinkage' on the tip of the pin that forms a slight basin. This might indicate a factory error short pour, or I don't know. Just speculating here. I haven't seen this on other belt pins.
Along with Mat's recent belt which I'll add soon, I'm sure there are a good few more variations out there.
