The Patterson-Gimlin Footage.

[putnam6]

I read somewhere that the order was placed for the suit with custom modifications to the head and some extra fabric to be sent along with it.

The building technique, latex molding, is not long lasting. It would have rotted away within 20 years of making if cared properly. Skin oil actually degrades latex. You have to clean it and treat it with caster oil to get latex to last.

As the suit maker, the father, is no longer with us, he can't demonstrate how to make one himself. Also, that technique is commonly available as do it yourself instructions for making fursuits on the Internet now. It was not commonly available knowledge at the time it was made.

This is what makes this event so fascinating, Id counter I read that the makeup artist for the original Planet of the Apes said unequivocally the tech to make the PATTY suit was not available contemporaneously to the film.

Isn't more likely the modest costume maker company, wanted the free publicity as the company that dresses Patty. 
  

Morris' wife and business partner Amy had vouched for her husband and claims to have helped frame the suit.[sup][242][/sup] Morris offered no evidence apart from his own testimony to support his account, the most conspicuous shortcoming being the absence of a gorilla suit or documentation that would match the detail evidenced in the film and could have been produced in 1967.

A re-creation of the PGF was undertaken on October 6, 2004, at "Cow Camp," near Rimrock Lake, a location 41 miles (66 km) west of Yakima.[sup][243][/sup] This was six months after the publication of Long's book and 11 months after Long had first contacted Morris.[sup][244][/sup] Bigfooter Daniel Perez wrote, "National Geographic's [producer] Noel Dockster ... noted the suit used in the re-creation ... was in no way similar to what was depicted in the P–G film."[sup][245][/sup]
Morris would not consent to release the video to National Geographic, the re-creation's sponsor, claiming he had not had adequate time to prepare and that the month was in the middle of his busy season.[sup][citation needed][/sup]
 
Film industry personnel[edit]Movie production companies' executives[edit]

• Dale Sheets and Universal Studios. Patterson, Gimlin, and DeAtley[sup][200][/sup] screened the film for Dale Sheets, head of the Documentary Film Department, and unnamed technicians[sup][132][/sup] "in the special effects department at Universal Studios in Hollywood ... Their conclusion was: 'We could try (faking it), but we would have to create a completely new system of artificial muscles and find an actor who could be trained to walk like that. It might be done, but we would have to say that it would be almost impossible.'"[sup][201][/sup] A more moderate version of their opinion was, "if it is [a man in an ape suit], it's a very good one—a job that would take a lot of time and money to produce."[sup][202][/sup]
  
• Disney executive Ken Peterson. Krantz reports that in 1969, John Green (who owned a first-generation copy of the original Patterson film)[sup][203][/sup] interviewed Disney executive Ken Peterson, who, after viewing the Patterson film, asserted "that their technicians would not be able to duplicate the film".[sup][132][/sup][sup][198][/sup][sup][204][/sup] Krantz argues that if Disney personnel were unable to duplicate the film, there is little likelihood that Patterson could have done so. Greg Long writes, "Byrne cited his trip to Walt Disney studios in 1972, where Disney's chief of animation and four assistants viewed Patterson's footage and praised it as a beautiful piece of work although, they said, it must have been shot in a studio. When Byrne told them it had been shot in the woods of Northern California, 'They shook their heads and walked away.'"[sup][136][/sup][sup][205][/sup]
  

Bill Munns[edit]Bill Munns, retired, was a special effects and make-up artist,[sup][206][/sup] cameraman, and film editor.[sup][207][/sup] He argues that Universal and Disney were not the most knowledgeable studios to consult with. He says that Fox, MGM, and special effects artist Stuart Freeborn in England, "who had just completed his groundbreaking ape suits for 2001: A Space Odyssey", would have been preferable.[sup][208][/sup]
Munns started posting his online analysis of the film in 2009 and summarizing it in the online Munns Report.[sup][209][/sup] In 2013 he and Jeff Meldrum co-authored three papers in Meldrum's online magazine, Relict Hominoid Inquiry.[sup][210][/sup] In 2014, Munns self-published When Roger Met Patty, a 488-page book incorporating material from those articles that analyses the film and film subject from various perspectives.
He argues the film depicts a non-human animal, not a man in a fur suit. He proposes a new diagnostic test of authenticity, at the armpit: natural concave skin fold vs. artificial vertical crease.[sup][211][/sup] Munns' analysis has been featured in an episode of the History Channel series MonsterQuest.[sup][212][/sup]

for fun I looked up Morris Costumes pretty amazing if this is the original company regardless here's their 2024 Deluxe Gorilla costume. Let's put it this way if it's fake and it was from Morris, Patterson/Gimlin likely remade the whole damn thing
