FOR LOT OF 10 ITEMS SHOWN IN PHOTO

This is for a vintage Bell Labs Western Electric photo mask for integrated circuit wafer manufacturing. From the 1970's &1980’s as were many of the items from this collection. This item would look great framed and lit from behind. I am not sure of the history of these things and what they were used for but they came from an employees estate so they were all used and created by a Western Electric employee. They are both 4” by 4” in size.

I have more of these and will be listing them as well. Will combine shipping.

This one is marked October 8, 1976.  Note that there is a small chip out of one corner of the glass.

This came from the estate of a retired Bell Labs engineer, obviously. They worked out of the Bell Labs Western Electric Mask Shop in Allentown. Two photos are the end show the box that most of these came in. This box is NOT included in the sale. 

Bell Labs Western Electric Wafer Photo Mask Glass. Condition is very good overall. This one is glass so you can see more normal wear on the glass. For parts or not working. This has been in storage for many years. It has minor scratches and the like on it from use but otherwise it looks great. NOTE: Also including a photo of the box label it came in with others however the box is NOT INCLUDED.

Shipped with USPS Priority Mail or similar.
