I have an early (DS serial # prefix) DSA SA58 FAL, 21inch barrel with the DSA flat top cover and 14 20rd metal mags. It has around 600rds through it. I bought it around 20 years ago.
I haven’t been following the FAL stuff for a few years, and a friend expressed interest in buying it, but I’m not sure what things are going for these days.
I’ve checked some auctions and various EE postings and assume it would be in the 1,500-2k range?
