American Optical Cat. 138 10x WF Eyepiece Lens

Description

Listed here is a American Optical Cat. 138 10x WF Eyepiece Lens.  It is a fairly old piece as you can see the identifying information is engraved into it rather than printed.  I struggled to get the details on camera.  I forgot to take more photos of this piece before listing.  Feel free to request more photos.  The vinyl sticker is there for inventory purposes and comes straight off.  You get the exact unit(s) seen in the pictures.

I do my best to ship as soon as possible upon payment.  Smaller items tend to be shipped same business day or next day, but is not always the case.  Shipping should be expected within 72 hours of purchase, provided payment is already made.  If the shipping and handling time on this listing is mentioned to be exceeding 3 business days, it can be assumed that I am currently away and that the S&H time will return to 3 days once I am back.
