The last time I remember seeing Westys like these being sold was around 1984 or so...so these may very well be at least 28-30 years old.

1973 or 1978, the date code repeated every 5 years in the 70s. You need to see if the electrodes have the extra twirl or not to pinpoint the year.

the twirl is the short segment in the middle of the filament made of several large coils. modern electrodes tend to not have that, just coiled coil across the entire length.

time to get out the laser....edit
no twirl.
probably due to conditions in the lamp but one end of each is near eol and the other is clean.
have a nos one that says "with titanium" on the sleeve.
