Antti can you please include an e-mail address or contact me so I can send you out Durant Vehicle Registration Form for details of your Locomobile. Thank you
Where Are You From? Mississauga Ontario Canada
Do You own a car built by Durant? 1933 Frontenac C-400 made by Dominion Motors of Canada
Could these been from interior/curtain lights which are mentioned in the locomobile manual?
