Marzocchi Fork Manufacture Date

Nov 2015
I recently sent my base 1299 Marzocchi forks off for a rebuild, but when i received them back I noticed that the year of manufacture that is cast into the bottom of each leg was different. One is a 2014 while the other is a 2015. I've searched ebay ads and such, but all of the Marzocchi fork sets I've seen have the same year of manufacture between the left and right forks. Unfortunately I did not document this before sending them off, but for anyone who has a base model 1299, do your left and right legs match? The casting mark should be above the axle on the inside of each leg. I bought the bike new and it has never been worked on by anyone other than myself, so I'm just trying to determine if I actually received my actual forks back...
