I have a Walther PPK/S Stainless Steal, made in Houlton,Me. by Smith & Wesson. It is called the "Royal Oak 1 of 500 Ltd", being #137. It is almost completly covered by Oak-Leaf engraving and has carved wood grips that look like cherry but not sure. The gun is un-fired exept for one factory test(included). I can't find this gun listed anywere and I have six big books including the BlueBook! I think it was made in 2004-5? Just a guess. Can anyone tell me more??? Thanks.
