Yes, Meeko could very well be an Olde English. But then he could be an EB mix, not necessary OEB.
You can kinda look at a bulldog and tell that he's an EB as opposed to on OEB. The EBs are short and wide. The OEB has a more square look. The OEBs have a slightly longer snout which is why they don't have the breathing issues of the EB. And, they don't have as much wrinkles. And the front legs are straight down from shoulders to the ground with the "elbows" pointing back. The EB "elbows" are turned out to the sides giving that exaggerated bow-legged look. The head and chest on an OEB is massive and his front legs are wider apart than the hind legs but the over-all look is well-proportioned to the rest of his body whereas the EB head and chest looks more forward-heavy. OEBs are much bigger than their EB counterparts and the OEB is also more athletic.
Now, in any case, the only way to know if your dog is pure EB or OEB is a pedigree. Without the pedigree you can't really tell whether he's an EB, OEB, or any other bulldog mix, so you can only guess at it. There are AKC EBs with a pedigree that don't quite meet the AKC standards and would look a bit more OEB than EB.
With my dogs, Bullie is non-AKC, Angus is, but Bullie looks more like the standard EB than Angus is. Angus has the massive chest but it's more balanced to his hind legs which allows him to swim whereas Bullie's chest is a lot more massive than the rest of her body that she can't get enough power in her legs to swim. Angus also is very athletic. He's a smaller dog than Bullie is (according to his parentage) and tolerates the heat of the car in Florida summer much better than Bullie.
Hope this helps.
