Yes, its a very good point not reproduce anything including a decal without permission. In this case we have done the proper patent and trademark searches and found nothing from the company and along those lines the company has been out of business for over 100 years.
I did read about the history of the decal, but was concerned that it may have not come on something from the teens. Most everything I see from then have a tag of some sorts riveted on. This is a thin walled cylinder that held oil and would be very hard to rivet a tag on and keep it from leaking.
I just want to be correct in the restoration and thank you for everyone for their comments and concerns.
