Radiography Remote Control & Guide Tubes (Industrial Nuclear Co). YDA35, AOO7SS

Description

These 3 parts are used in a gamma radiography projector to bring the radioactive source, usually radioactive iridium out of its containment box and into the guide Tube where the gamma rays exit and will allow the user to use gamma X-ray radiography to x-ray metal parts to check for material defects.
They appear in new condition but they are lacking a factory box, if they even come with one.   They are USA made and are of very high quality because ultimate safety is definitely a concern when dealing with gamma emitters.
I have personally checked them for any radioactive contamination and there is none.
I'm listing these for a very reasonable amount, as they are extremely expensive from the manufacturer.
They look new and show no signs of wear.  If you have any questions let me know thank you.
There is a note saying they were used with an Amersham source projector but they may also work with other projectors as well, check first.
