Hard to say as they both look different in the top 2 pics. The only other last they could have been made on is the c461 which has a pointier to but you'd also see a difference in shape throughout. I'd check with White's but I'm pretty sure it will be down to how they were lasted not the last itself. I've spotted these differences a fair bit on repeat stock orders, particularly with the thinner leathers and soft toe's. Good luck.
