UF-353M 76mm High Explosive Round for M1927 Regimental Gun
This round was found together with the case showing that is a "353" with the black stripe at the neck - reduced charge for the M1927 gun. The projectile retains its original paint and a hint of its markings. I am not sure of the date on the projectile. I know it was captured by the Germans; it was found with a French fuse with a waffenamt on it. The powder bags and cardboard tube also show the reduced load for the M1927 short barrelled gun.
Thousands of these rounds have been found in Poland in the last few years with the French fuses pictured. The fuses have waffenamts on them. I only have the one picture shown above that has the nomenclature as UF-353M. However, the markings on the case agree with your convention: UF-353.
I have here a new addition showing the black stripe indicating it was loaded with a reduced charge for the short barreled M1927 gun. The case was originally made in 1916 for the M1902 field gun, and it was reloaded in 1933. The markings show the complete round was named "UOF-353-T". I do not have this round in my chart. "UOF" means it should have the standard OF-350 high explosive projectile. My research shows this should be marked as a "UOF-353M". Another mystery.
Here is something new. I cannot even find pictures out on the web, and the WWII Russian ammunition manual in the download section does not even cover this round. Its condition is not great, but the cone is still inside. This round is for the M1943 regimental gun with the short 160mm long case.
Thanks to our hungarian friends we at least have a drawing showing the diference between the A and M version.
Nice round Steve, looks like the collection is steadily growing.
I am not sure about the tracer on the A version on your picture.
I do not know the answer to your question on the tracer Bob. I only had two references to this round before you added your pictures - thank you. I found the reference that I attached on the internet; it is not a Russian manual. I do not know who put that together. The other reference that I have is in German, and I found it here on BOCN or w2kammo.com.
with regard the two without their ballistic caps, have you come across any reference that shows which is mk1 and which is mk2. (I.e which was designed first).... Or is it conceivable one was from one manufacturer and the other from another, but the design varied due to their manufacturing capabilities and techniques varying?
The only reference that I have is the Russian artillery ammunition manual in the download section on this site. It only shows the sheet metal version. I do not know which came first.
There could be as many as five variations for the BR-350 armor piercing projectile for the Russian 76mm guns. Here are two which my documents both show as BR-350B's. One has the larger MD-6 base fuse, and the other has the threaded plug with the smaller MD-5 base fuse. The MD-5 is also used in 57 and 45mm APHE shells. The other variants which may exist are BR-350A and C models which use MD-7 or MD-8 fuses. There could also be a variant with no HE charge and only a tracer element.
On ebay, I found these images from a Russian subcaliber ammunition manual. It covers 37mm through 85mm. It only shows the sheet metal version for the 76mm. Note that every other APCR round has an aluminum nose (except 37mm). For this reason, I think the aluminum design came first.
Here is my new favorite Russian 76mm high explosive. It was captured by the Germans and given the "284" mark just as in the document supplied by Grief above.
Do you think you can maybe help me with some better pictures with the markings on your shell? I am talking about the ones in black ink. They do not seem to fit neither the German nor the Russian type of markings.

Am I correct with this? Are there any other characters you can see in this group? Also, are there other markings on the other side?
I do have something in my mind, but I would not want to rush with my hypothesis.
You are correct on the markings. The only other marking on the projectile is "KTM-1" for the fuse designation on the other side. I do not consider the markings unusual as I have had almost twenty such rounds marked in a similar fashion with prewar dates. I only have a few remaining, and I will see if I can get you some more photos.
I have four OF-350 remaining. Only this one example has these types of markings. Two others are the more traditional with "OF-350" and one has another unique type markings that are covered in another post.
