Absolutely.
This was in Roosevelt, AZ in the 60s and early 70s, during visits to the local bait & tackle store. The bulbs i saw were clear glass, dunno if the flicker woulda been diminished any if they had been frosted glass.
Conversion to 60 cycle didn't come until 1973. Here's a bit of skinny on the frequency standardizarion project..
