Merry Christmass, Steve I appreciate your offer! A pork pie becomes a mushroom, and mushroom and Raiders go tegether
An AdventureBuilt turned into a pork pie might have to sit for a few months? to distort?
And a Merry Christmas to you my friend! Yes, or just steam it alot after the crease is in to set it. Better though would be the factory block as they use a tipper, or the female image of the top crease to press it into the crown. This would seem to me to be the sort of hat that you are referring to when you speak of the telescope crown being used for the Raiders fedora. That would raise other issues. That is, did HJ do the factory telescope creases at this time? Or, were they still doing the tradtional creases. What I mean by that, is back in the day when you went to buy a hat, many times the salesman would pull an open crown hat down and the creasing was done by him to suit whatever style the customer wanted. Later on, I think, they added the factory creases, the ones that were mechanically pressed into the crown of the hat. But whether or not HJ ever offered the factory crease interests me. Now, most of the factory creases of the telescope variety were generally stamped into stiffer felt, for obvious reasons. Under the heat and pressure the top of the stiffened crown also distorted under this procedure. Hard to get a nice looking fedora from a traditional stiff telescope crown, that is, the complete look. But. if the soft felt of the Raiders fedora was handcreased at one time into the mentioned crown crease, then popping it out, and restyling it into what we see as the Raiders fedora would be a moot point really. That should be obvious as well. That is the beauty and desirability of the soft felt hats. You can style the same soft felt(and the Raiders fedora was traditional soft felt, unlike the hats HJ sold us during the 90's) into various styles, and change it up at a moments notice with no dire effects on the hat. So, this is just some more things to think about. Fedora
Does anyone have a larger version of this black and white from Raiders? !!!! 
!?!? - The pork pie LINE seems to be entering the left side of that little dent, and I'd like to get a MORE DETAILED view! ALSO, there looks to be a little LEDGE at the back top corner of the crown, possibly an extension of this pork pie line. I've bashed my hat to have that ledge at the corner too - it just happens easily with a pork pie..... The black and white is someone's avatar, and it's only 100 by 100 pixels. If I enlarge it, it pixelates. HELP!...
........Look at the stick crates in front of Indy's nose in the big b&w pic, and notice they are not there in the little b&w pic. Maybe the little one is a sharp studio 8-by-10 they took the crates out of in the printing process, or maybe someone here photoshopped them out and cranked up the contrast and sharpness? 
It just ain't that tall folks!! I have noticed that many of my hats that are shown here have too much crown. That would be the 5 3/4 variety of course, but it sure looks too tall at times, on us. 
I have started making the default Raiders fedora at 5 1/2 open which seems to match the film hat better, at least on most scenes. Fedora
I appreciate your offer! A pork pie becomes a mushroom, and mushroom and Raiders go tegether. 
That's the green hat. I haven't told you all about the other pork pie I bought, a black Pastoralist. Basicly the same hat with but with Imperial felt. 
One difference is the pork pie on the black hat seems to have been formed on a block, while the pork pie on the green Squatter looks like it was done by hand. If steam or water (or not) was used is anyone's guess. 
The "Z" fold of a pork pie is like a spring. An AdventureBuilt turned into a pork pie might have to sit for a few months? to distort? These Akubras are too low at about 3 inches on the sides, where the Raiders hat was probably between 3 1/3 and 3 1/2? Open crown height on these Akubras is only 5 1/4 or 5 3/8. ..........................................Concerning the B&W pics! I realize turning a pic into a 100 by 100 digital image can distort things, but the way that line entering on the left protrudes into the shadow is too obvious to come from the nice rounded shadow line of that magazine article's shot. I have printed photographic film images in a dark room back in the day, and I think maybe Lucas's guys altered that. All you have to do is block or admit light using cardboad masks during the exposure from the projector onto the paper.
The black hat is flawless, obviously stamped out like a cookie cutter, yet the distortion is similar. I don't have a clue which way HJ might have used.
The other white bump above it should be the line of the inner fold of the pork pie.
