A bit of a size comparison on the Arnaud per member request. My apologies in advance for the crappy photos, I am not set up to do dbl wides.
Here are the Arnaud up against a couple widely recognized Ray Bans-
1. 3025 58mm Large Aviator
2. 2140 Polarized 52mm Wayfarer


Both of which are Brand New and for sale by the way in case any one is interested. Looking for $110 for the 3025 and $125 2140
Sorry ET no 52mm 649's at the moment for a side by side. The closest I could come up (which is not very close) is this pair of 51mm Persol 2911 also for sale to SF members for $195

I hope this helps. Let me know if anyone needs more pics of the new pairs and I will try to get back to this thread with more TF in a day or two. Thanks.
