JDSU Green HeNe laser 543.5 nm (model unknown, 21" long) with power supply

Description

For your consideration I am offering one JDSU green HeNe laser, with power supply.  It works and is very bright (I have no way to measure the output).
Note: The label was missing on the laser, so I can't say with certainty what the model is.
It's history: A number of years ago when JDSU downsized, they disposed of a huge amount of their laser related parts and equipment.  I was lucky enough to be in the right place at the right time and secured loads of the cast off items. Those of you that have purchased from me in the past certainly remember lasers-a-plenty.  This laser (and the other I have listed) all came from the same big box-o-lasers.  So I am assuming it's a JDSU model, but it's length, 21", doesn't match up with any info I've found. It's remotely possible it was an engineering sample. I did actually get (and sold) a prototype compact UV laser from there that never went into production. So, there you go, history.
I've saved this one (and one other, red, listed separately) from a lot of them I got from JDSU a few years ago.  I expected to be inspired to make a project with them, but I've found other outlets for the maker in me.  I hope you can put it to good (and fun) use.
I may ship the power supply and laser separately to reduce possibility of damage.
Thanks for looking
