Nice work. But front whells should be changed left with right to be same rotation direction as rear. But interesting fact that on some pictures right rotation is for front whells. I dont know where is correct.

I'm note sure its 1915. Its cames with MPC 1/25 CHRYSLER ROADSTER 1932 but looks very close what you want. Probable its Indian.
And also BMW, single and with side car. Also not sure about year.
