Any Mondonico experts out there?

I’m hoping to narrow down when a recently acquired Mondonico was made. About a decade ago, I borrowed a Mondonico EL-OS with the monostay seat stay from a friend for awhile. I absolutely loved the ride but reluctantly I had to return it. That set me off on a hunt to find one in my size. Over the years I have came across several Diamonds and Futura Leggero frames, but no EL-OS with the monostay. Last September I found another Futura Leggero, this one with a monostay seat stay. Of course I had to buy it. I’m by no means a Mondonico expert, but this is the first Futura Leggero with a monostay design that I’ve seen. It’s made from Nemo tubing, and the ride is fantastic. It has a 1” threadless fork that is original to the bike. The seller didn’t know much history of it. It’s built with a Campagnolo Record 3x10 groupset. I’m curious if anyone might be able to help identify when it was built.
