Hello Lorenz and thank you for all the information and the links to Federico Malibago's web site. It seems as dating these can be just a bit tricky. On the shape of the hilt he says "
At some point between the turn of the century and the 1930s, gunong hilts gradually changed into the more familiar pistol grip." Then I found this on the same site. http://home.earthlink.net/~federicom...es/gunong.html Which he dates to the late 19th century. I know that the blade shape is different from the one I have posted but the hilt is quite similar in style.
Jose, thank you for your information as well as I really appreciate all the help that I can get even if it is not what I would like to hear. 
At the same time on Federico's site I also found this http://home.earthlink.net/~federicomalibago/megunong.html that has the same blade style as mine which he dates to the 1930's because of the fact that "the fittings are all soldered and not of common post WWII materials." The one I have posted it made of copper and what I believe to be swasa. I really need to get this tested to find out for sure. It is not the brass that would be more common after WWII. Also all the seems on the scabbard cover and the hilt fittings are all soldered on mine. There is not one piece of tubing used on it anywhere. One more point of interest is that this piece has a laminated blade and most of the post WWII blades that I have seen are made of monosteel. I will let the experts decide on the dating of this as I have no knowledge of these what so ever.
Thank you both again and also Federico for all your help.
Robert
