WELCOME TO THE FORUM
I HAVE NO KNOWLEGE ON THESE SWORDS BUT AS A REPLY SEEMS TO BE SLOW IN COMING I WILL MAKE A SUGGESTION. USE THE SEARCH FUNCTION ON THE CURRENT FORUM FOR VOC AND THEN GO TO THE FORUM ARCHIVES AND SEARCH THERE. IF YOU STILL DO NOT FIND THE INFORMATION YOU ARE LOOKING FOR SEE WHO THE MOST KNOWLEGABLE FORUM MEMBERS IN THE POSTS ARE AND SEND THEM AN EMAIL. GOOD LUCK
