Preban Olympic Arms Sale Question

[CarouselOfProgress]

I bought this years ago, but I now I'm looking to sell it. Before I list it on Gunbroker I was curious if anyone here has dealt with Olympic Arms issues recently. It's been known for many years they lost their records due to a fire, but now even their website is down. The best resources are AR15.com etc. The records show this serial would have been manufactured from 6/20/94-7/20/94 but not much more.

This will need to go through an FFL as I am in CT, but do you foresee any further complications due to the OA records issues or an FFL declining to do the transfer?
