Looks like old Indian or Harley style.
The owner used what he had, the originals too expensive? 
So you all wonder why that bike was done up as it was? It could have been a girl's/wife's bike to match their husband's bike.
I recently lost a good friend in December, a retired Master Gunney Marine, that back in the 70s he toured cross country, San Diego to Springfield MA and back on his 68 Harley and his wife along on her CB350/Four that was outfitted to match his Harley. They were members of a local riding group, the Paladins, they wore matching uniforms and would do parades and exhibitions as well as competitions together.
Unfortunately I didn't get a copy of the picture of his wife's 350 that he showed me when we had our storage units across the alley in Oceanside. Sure do miss Ken. A heck of a guy. And lots of riding stories.
The 1st 3 pics of his Harley from 2011, second 3 are of Ken exercising it in 2020, the last pictures of him that I have.
