inspiration for creating Indiana Jones?

Every time I watch a documentary about making of IJ trilogy I hear about those "old serials" & other stuff from which things & bits were borrowed to create Indy. But I've never seen specific titles being mentioned.

Do we have experts here to answer my question? If I want to see old books/comics/movies that contain "prototypical" Indy, what should I look for?

The sources for Indiana Jones are almost as numerous as those of star wars.

I know the Stewart Granger version of King Solomon's Mines is one, and another is gunga din from rko pictures.

Treasure of the Sierra Madre, CasaBlanca, The Maltese Falcon, North By Northwest.  Zorros Fighting legion, Zorro's black whip.  Tarzan.  The greatest show on Earth (lion tamer) .  Don Winslow of the Navy and Don Winslow of the Coast guard.  Tailspin Tommy.  The spy smasher.  Terry and the Pirates comic by Milton Caniff.

Haggard's novels or the film adaptations of them Like She, and the already mentioned King Solomon's mines.

The movie Stagecoach which was also an infleunce on star wars similarly as Tarzan and the works of Edgar Rice Burroughs were.

The Pulp and dime novels of adventure fiction from the 30's and 40's.  Nothing in particular has ever been told to fans as far as source hunting goes.

Of course Lucas interest in the social sciences, archeology and history and world mythology also had an impact on the series.

Again it has Never been proven a source but a real man named Vendel Jones i believe searched for the Ark of the Covenant. 

Oh of course the often forgotten source of James Bond, It was almost meant to be that Sean Connery who was bond would be indiana jones father in the movie because that was the original impetus for spielberg to make the movie having begged cubby broccoli to make a bond movie.  He had about as much success with Ion productions as Lucas had in trying to buy the rights to flash gordon from king features.

What sources are mentioned in the making of indiana jones by Rinzler?

I know a bunch of film serials were mentioned in Great Movie Stunts, and Making of Raiders of the Lost ark.

Ok so apparently Doc Savage was also a source and so Was The Lone ranger.

So what doe you now have to sit down and watch the entire catalogue of The republic, and Universal Serials.  Which are all forgettable and bad.  One which people consider to be bad was the high water mark and was the most expensive produced flash gordon.

I would also like to check out secret of the incas, But it exists as a so called public domain source on ebay according to a seller.  I don't know if this is verified It may just be a bootleg.

I read one review Claiming to have seen the best copy so far on dvd that was a bootleg apparently telecined from a film print.  If the movie is truly public domain then anyone who owns a copy can go down to a lab with a rank telecine and get it transfered.
