The bell\reservoir cracked when attaching a new seal-off stem. The bore is intact so I may try again but for now.... :-(
actually, would it be possible for you to take your OC out and look at the part number? im curious if you have a broadband one. mines a lame 632.8 one but ive heard the standard is 612-640nm. the tuning prism however is coated for everything possible so it doesn't care. thats why i can tune to orange with an external OC.

I’m just glad it was savable. Nice job! Just a clarification for lpf, this isn’t the largest helium neon in the world but it is definitely one of the biggest commercially sold ones! Nice pics too!
