Unconverted are between 900-1200 right now. Converted can be well into the 2k range depending on the extent and quality of conversion. Also, if you bought these 20 years ago, are the receiver magazine wells dimpled? If not that hurts the value. We’d need to know if it’s converted and dimpled to give a good estimate. Post up some pictures and we can go from there.
bolomauser: If there had been some way to know the approx. quality of a stranger's conversion work, I gladly would have sought out a local version in 2015 or so, on Armslist.
I had bought two "nib": both the .223 and 7.62x39, but having neither the skills nor tools, soon sold the pair. No way would I use a decent, or very nice gun as a first-time test lab to develop the skills.
One thing is a very clear impression: when racking the bolt, and even shooting both - they feel somewhat superior to most of my imported AKMs (some are all-matching). Part of this feel could have been their near-'new' condition.
Only my fairly unique Czechpoint VZ-58 (...Not a variant, totally different....) really reminds me of the "built as one original weapon" feel of those nib Saigas..
