The research I did led me back too the 20s, the 1st Christmas bulbs too come out were clear and then they made green is what I understand what I read.  I would say 20s but they may be earlier.  I do have the strand these go into but I could not get them too come on, 4 strands around 6ft long, I am not selling those but they will come with the lites because I do not like throwing older things away.  

Maybe someone smarter than me can get them too work.  Again, I am not selling the strands but will ship them with the lites.  And too add I did hold most of these bulbs up to the lite and the connector from stem too stem is intact.  This is truly a super rare group of bulbs.  And the exhaust tip is unusually prominent on all the bulbs.
