Unless your next door neighbor is a collector of Gas and oil also, how else would you learn if its not in books, and maybe you don't know where to get them. People just start collecting stuff and it snowballs from there.
Thought that this was the place where you had friends and fellow collectors to help you. Where else can a guy from San Diego or from Maine help a guy in Canada or Texas.
Just get back to helping the other guy with your knowledge whether you are 50 years or 1 month into this hobby and past time. Show pictures and yes give suggestions.
Everything changes from the gas prices 50 years ago to bread and milk now. Try getting your doctor to make a visit or go to the dentist for under $100.00.
Prices are tough, finding it still is great.
