This is for 12x Eberline SPA-3 housing as pictured. These came from a lab and had their photomultiplier and crystal removed. They will come with most of the parts shown (some have more and some have less). At the minimum, you will receive the caps and the tubes. You may receive the additional parts but not every tube was opened to verify contents. Most "rattle" indicating parts are there. 

Housings are for a 2" x 2" NaI(Tl) scintillator crystal scintillation detector.

Please look at the pictures and search the part number online for further specifications and details.
