2 Pocket Slide Rules, Sun Hemmi Japan & Made In England w/Original Cases Leather

Description

Sun Hemmi: checking online, the manufacturing date code NL is December 1963. I don't see a model number. The sliding part has markings on both sides
The other was
made In England and has no other identification. The sliding part has markings on one side.
They both appear to have their original cases.
My father was a draftsman and engineer in the 1950's through 1973.  These were his. What you see is what you get.
This item comes from a smoke and pet-free home.
Please email me if you have any questions or need more pictures.
FYI, I often use/reuse shipping and packing materials.
I have sold more than twice as many items as I have feedback for so I leave feedback for buyers after you leave feedback for me.
Many of the items I sell are used or vintage items. I try to be as accurate as possible in the description and pictures. I'm not an expert on anything and cannot describe every detail. Please look closely at the pictures. It is your responsibility to read the description, look at the pictures closely and ask questions before bidding.
Thanks for looking!
