I have the 170300, it has the fishscale serrations which is the way I like it. Had a chance to get the wavy model and passed, they did offer it in just silver finish also. I believe there was a earlier two-tone fishscale run maybe a no-dash version but it would probably have a different sku# also. I would guess no more than 500 of the wavy two-tones, good luck with your search.
