I have a 26” Belgium Lightning round knob in original condition. Seldom shot it since M/F. Think I paid $1600 for it several years back since I did not have one and coveted them since the ad inside every hook and bullet mag had them at 325 when the A5 was less than 200. I gather from this post that it may be worth more? Really should be no surprise since so many newer junk Guns bring so much.
