I see some nice stuff in your shop!! Looks like a 50's Caddy bumper, some cool motorcycles, perhaps an Austin Healey? It's not what you asked, but I can't help but notice. How rude of me!! I think comment #6Jay81 nailed it, but the others have contributed nicely too.
My 2 cents I posted somewhere on the Cabe in so many words before, I'll never know where, so again/one man's opinion:
In reality unless a bike is bone stock original, a TRUE barn find, or cellar, warehouse, yard sale etc., it is a Frankenbike in my humble opinion. Unless the bike can be documented from factory, original owners etc., anything can occur. I mean many bikes in many collections have been restored ( in part or whole), parts upgraded, accessories added all to a degree or goal of originality ( in most cases) or a Custom or look to meet the owners taste. Lots of collectors in the hobby own original examples. Sometimes ( more than often) the word "original" is misleading and bantered around without thought or conscience.
Lets face it, people like to personalize things. Bikes are no different. Remember what kids did when you were younger? Took stuff off, put stuff on. As mentioned, this bike is an assortment of parts and someone's Custom. I think to try to steer ( no pun intended) it towards any year or model would just be throwing money away UNLESS it's what makes you happy. To ever recoup the money from selling as a particular year and model is VERY unlikely. Look at guys cars resto's. Knee deep $$ in a car they'll never see if they sell. I have one, but I love the car!! I have some bikes like that too. Do I care? Not really because I do it for fun and enjoyment, not investment.
To quote Jay81 again/see bold below. I think for your satisfaction and enjoyment ( with value given some consideration) there are better examples out there with more ( or all) original parts and year correct..."different project that's more complete/original to begin with."
Cheers, and enjoy the hobby. Looks like you have an assortment of interests. I'm part of that group as well!! Ha!!
