Looks like it's been tickled up a bit, like you say Ake, windscreen, speedo, battery or tool box, seat covers, front wheels 3-1/2's? painted hub bolt heads and hand rail on the seat, no side lights.
We've discussed this picture many times over the years. It is a 1915 Canadian made touring in Southern California with fork mounted headlamps. It has a battery box so likely it has some sort of starter generator conversion. The windshield brackets are an Apco accessory same as the ones on my '15.
It's a great photo. I like the top boot detail.
