They look so similar. I can't find the difference until see the stamps.

Great question, answer below. (I'll edit your title)

From a 1975 catalog:






From a 1960 catalog. The Sandblast has been around for a long time, I feel that the Pebble Grain was a 1970's introduction, but that is not definitive.

Thank you for your help. English is not my native language. Maybe some of my words fail to convey the idea. According to the catalog you posted, the sandbrast pipes were earlier than pebble grain pipes. Am I correct?

Understood!

I don't have exact dates, but I believe the Sandblast was a finish long before the Pebble Grain was released.
