New, unissued condition. They have easily removable paper tags that may differ in color.
Russian size 50, approximately US size 34/36
Russian size 52, approximately US size 36/38

Regardless of the size markings, the sleeves on these seem to measure a fairly standard 20-21" in length from shoulder seam to "cuff". As an undershirt, they probably weren't intended to always reach all the way to the wrist - and, in many cases, were probably worn pulled back up the forearm well toward the elbow. Please remember, since the servicemen who wore these were generally slender and always very physically fit, these shirts tended to be worn quite snug.
As worn by the famed Soviet Morskaya Pekhota (marine infantry), the tel'nyashka and the "Donald Duck" sailor's cap were usually the only things that distinguished a naval infantrymen from the other ground forces, as all other equipment and uniforms were the same.
