Mr. Lazenby's screen time in Gettysburg is very brief, but here is some historical comparison. Here is Mr. Lazenby, costumed in the uniform of a Confederate General, in regulation cap, gray frock coat and trousers, etc.
Below is a model wearing General Pettigrew's actual dress frock coat (steel gray), with General Pender's pants, and Gen. Robert Ransom's cap. This Pettigrew coat is in the North Carolina Museum of History collections.
At Gettysburg national military park is a frock coat ascribed to Gen. Pettigrew, though its provenance states it was captured by federals in 1862, so not worn at Gettysburg evidently (who knows what exactly he was wearing at Gettysburg?). It is the one shown in the "Echoes of Glory" Time-Life books of uniforms of the Confederacy about 1990.
Because I, like many, had practically memorized all the uniforms photographed in the Echoes of Glory books, including Pettigrew's brown/gray coat; on seeing the movie I immediately noticed they made Mr. Lazenby's Pettigrew costume a sort of brownish-gray, like the above coat: I assumed the movie costumer's might have cracked that same book, so was slightly impressed. To show what I mean, compare with the cadet-gray of Stephen Lang's "Pickett" costume:
I assume it lacked the better tailoring as demonstrated for say, "Pickett" or "Longstreet's" uniforms because of the small role, and the general's insignia is "sutler's row." Regardless, as mentioned, Pettigrew's brown-gray colored coat was evidently no longer in his possession by mid-1863, but if the movie maker's did make some effort to replicate any Pettigrew uniform in any measure, then way to go. Of course, perhaps the whole getup is off-the-rack sutler-row.
Perhaps not hired for a direct resemblance to Gen. Pettigrew, it is evident Mr. Lazenby cultivated a short mustache and goatee for the role. Sure it's too short, but I don't mind, as his preparation spared the use of more false-whiskers. In fact, Hurrah for Mr. Lazenby! Below is a comparison.
Hey, I notice James Permane is the fellow standing behind Mr. Lazenby in the above image. He might have details about "James Bond's" appearance on the Set of July 3 at Gettysburg!
