I could be and hope I'm wrong but I usually attribute that effect to poor sand casting and mostly attributed to reproduction work. I'm not a big jarhead though.
Or a Marine.
I have always thought that the condition resulted from a rust pitted mold. When it is found, it is most often in small areas. Sometimes the base will have an orange peel surface. Sometimes it is the shoulder or one side of the jar. Intensity also varies greatly. This jar is very intensely textured. The surface feels like worn out, coarse sand paper. The condition covering the entire surface is not encountered frequently. Rust as a cause is only my personal guess as I don't recall ever discussing the cause with another collector. I know that several advanced collectors watch this forum. If someone wants to add to the discussion they would be welcome. I am used to being told that I am dead wrong, I have been married for almost 49 years.[] George
I have not examined a ton of the orange peel jars, but now that you mention it, most often it's just a little bit here or there, on the flip side, a whittled jar , be it heavy or light tends to cover the entire jar. I will agree with you on the rust theory... 49 years...Wow... She must be a real fine lady to tolerate your dead wrong for so long[]
