Neither looks like a 'normal' Conlon signature. Also, to me the photos don't look like Conlon's work.
But I could certainly be wrong. After examining a piece, if there is a question like this, the next thing I ask is "does it make sense for someone to falsify the item?". In this case, the answer is "no", since they were not sold to you as Conlons; however, if you were provided with back scans, the seller may have been trying to plant that seed, even though he knew they weren't Conlons.
Your best bet is to just study a bunch of Conlon signatures and make up your own mind. I just took a quick look at these, but when I have time I'll compare to other Conlons that I'm sure are correct and post again.
