Yes, I remember it. My sons used it to oil their baseball gloves.
I grew up in the 50s and early 60s. It took a lot of neatsfoot oil and a lot of throw and catch to break in a baseball glove.
It seems like the last time I saw one, it was nylon. Also made in Japan.
My first one was a Warren Spahn. He was a lefty but the glove was for a righty. I think it was a couple of years before I got it just right.
Brought back a flood of memories b/c my dad used it on his knee-high hunting boots; and my brother on his baseball glove.
Am I remembering correctly, did it have a really strong odor?
