The biggest tell was that the west bend 610/820 engines didn't come out till 1962, When I inquired about that on FB, the story I got was the bike is a "tribute" build to the original 610 powered bike from 1962 in the early pics, but the frame itself used there is the 2nd bike ever made. There are some other things you missed as well, such as the upper crossbar is not on, or moved farther under the seat the original WB powered bike, tank is different,etc..
Its a way cool bike regardless, and a great replication, I dunno If I would have went the "custom" route if that frame truly is the 2nd (or would that technically make it the 3rd? If you read the "history of lil indian" it states Troy bought the 1st one, sold it and then bought another 3, and sold them right away, and the add stated it one of the batch of 3) but what people decide to do with their bikes is up to them not us. History gets tweaked here and there or left out along the way sometimes, and that's a bummer for people truly wanting to get something put back together the way it was or to verify whats there when on an old bike etc..
