I really see no reason why his legion wouldn't have a larger strength. The internal rebellion was brief and didn't seem to do a huge amount of damage to the legion. Their tactics don't seem to result in large casualties either, so I really can't see why they're not much higher.
Besides, they're one of the 3 legions to stand on Terra. They need larger numbers because they're going to lose thousands during the seige. It's going to make a dull seige of Terra if the Loyalists have a few thousand space marines to go around.
By dull, I mean that the authors are going to be handicapped by having limited marines to use in battles and they're going to end up reminding us over and over and over and fucking over again about how few in number the loyalists are. As an example I draw your attention to novels featuring Iron Hands, in which we're reminded every 5 pages that they're a small, broken legion.

Was surprised recently to be informed that the White Scars supposedly have the smallest of all the legions

Went over this in another thread somewhere I believe. But thus far, there has been nothing I've seen to suggest the White Scars were any smaller than the average. The Thousand Sons always have and always will be the smallest though.

Agreed. Without getting into another one of 'those' discussions about legion size again, we can all agree that Scars are barely mentioned in HH. The little information we do get on WS doesn't mention their legion size at all.
So the stuff on 40k wiki is unfounded speculation.

UNLESS, it's mentioned in the 40k WS codex, which I haven't read.

White it may have its moments at times, I wouldn't trust the 40k wiki since anyone can go in and change stuff. Lexicanum is more reliable in that regard.
