The tube in foreground is from May '84 I think, the other one note sure, Jan '85 if my eyesight is good.

Wow, there are some unused sylvania tubes at my great-aunt's house with this etch. So they're frrom the 80's

I believe that etch style or a similar one was used during the 70s and possibly the 60s too.

I've been told this was the later etch used by Sylvania Canada in the 80s. I guess they introduced it when the American Sylvania dropped the cross-hatch etch around 1980.

The lamps said made in USA though. The lamps have atleast thirty years of dark gray dust.
