Local fun shop has one of these, looks in decent shape.  Not sure what the consensus is on these, I had an Imbel L1A1 and loved the gun --bought a L1A1 parts kit and furniture for it back in the day, only thing that sucked was the barrel was used so accuracy suffered.  This one looks to be in 90% condition, what would be a fair price to offer ?  LGS is usually high priced on used stuff, but I know its been sitting on his shelf for a good year, hoping to make him an offer that works for both of us.

Can you check the receiver to see if it is a post ban parts kit gun, or a real L2A1 import?

L2A1 heavy barrel kit builds in nice and accurate condition go for a lot more than the L1A1 normal SLR.  

check past sales on FAL files.

Is that the one on Gunbroker with a buy it now of $3450?

No this is sitting on a counter in a tiny LGS.  I'm going to stop in and see what's he's asking for it.
