A-5 collection needs a 1997 model!!

Searching high and low for a 1997 A-5 (NR in serial number), since that is my son's birth year. I have been hitting Gunbroker pretty hard, but no luck yet. Any other site to recommend? Looking specifically for a 12 gauge, since that is what I have in my father's and my birth year. Any help would be appreciated!!
Thanks!
Doc
