Well I got the shotgun out this afternoon and really give it a good going over. It has a 5 digit serial number and after close examination I DO believe it was originally "polycoated". The rear of the stock has a darker area that is evidence that at some point it had a slipover recoil pad on it. That area is clean, shiny and in much better condition than the rest of the wood. The forearm is nearly void of ANY coating and the pistol/cheek area of the stock is badly flaking and the coating that is flaky is yellowed.

The metal is great however, I pulled the forearm off of it and the spring and mag tube looks like it is only a year or two old. Like I said I know for sure this gun has sat untouched for at least the last 22-23 years, so whatever wear/use it got happened early on in its life. The screws appear to be untouched so I doubt seriously that the gun has ever been apart. It should make one fine resto piece. I even like the large "FN" buttplate on the stock.

Thanks for all the info guys, I knew I could count on this site to get me pointed in the right direction!!!
