90mm T91 HE tank round...

[shelldude]

This is an inert U.S. Korean War 90mm HE tank round that is kinda scarce to come across. These were used in the post war M26E1 Pershing mounting the T54 gun, the M48 Patton and the M56 Scopion self propelled anti-tank gun. A couple unique features of the projectile were the steel rotating bands and the protruding tracer boss at its base. The inscription on the projectile reads: BHE- 1-2-1952-90MM-T91 while the brass casing reads: 90MM T24 1953 LOT NO SCV2-2. The T24 casing is identical to the M108. The MT/SQ M500A1 fuze is also dated 1953. The shells dimensions are identical to the much more common M71 HE.

Best regards,

Randall,

There is some additional T91 material on page 2 here:

There was a T92 WP projectile also, but I've never seen a real one. I wouldn't be surprised if USSubs or EODGuy has one though.

Sorry John, no 90 WP. This is the best I can do, not so pretty, but some original markings. My 75mm is heavily overstamped with no markings.

I do have a couple of fairly rare WP rounds though, an M325 105mm recoilless and a T numbered WP 175mm which is not currently in my digital files. Good luck in finding the 90 WP, I've never seen it either.

Thanks for the vote of confidence, but I don't have a T92 either. Actually I do not have a collection of large caliber. It is easier for me to collect the documentation on them. I have few items, mostly experimental or uniqe. My basement has no room now because of the collections. Large caliber roudns would really compound the problem. Nice rounds pictured above!! The T24 case was adopted as the M108 and the T24B1 adopted as the M108B1. Not sure of the relationship of the T91 to the M71. No doubt one of the T91 series was adopted as the M71, but I don't have a record of it. The T91 program development began in 1949. So far I have not run across drawings of either the T91 or the T92 in my files.

Hello John, Jeff, & EODGUY,

John, I don't know how I missed seeing your excellent post about the T91. Don't I feel like a dummy! I've been trying to locate a 75mm Skysweeper round for quite a while. Thanks for updating me!

Jeff, Thanks also for the photos of your beautiful examples!

EODGUY, Here is a photograph showing the details of the T91. It's the only one I've ever come across but the description provides very little information.

Best regards,

Randall

Yes, the T91 only appears as a drawing in the one manual that Randall has shown, and the T92 is described in following paragraphs.

Bob, I believe the T91 was meant to replace the M71A1. I'm thinking it is mentioned in the text in the manual that Randall pulled the excerpt from, but you know how manuals are. The military changed their mind two days after the manual was printed.

Randall, no reason to be embarrassed. I keyed in T91 in the search fuction here and it didn't find it. I wish someone would publish some helpful hints on how to find things consistently with the seach. It either says the word is used too much and refuses to display the posts or fails to show the post. I remembered that I was talking about hemispherical bases, so I searched for hemispherical, which it did find. Kind of irritating when an author struggles to find his own post.
