A cool vintage piece that's been around here a long time, we're super deep cleaning, so keep an eye out. If you know how to use this and it will help you, insured shipping is only $7.75 so good luck and have fun buying.

from online: If you are a lover of slide rules, or merely collect trinkets, then it would be difficult to find something more collectible than slide rules made by Keuffel and Esser.  Not only is this because of the enormous variety of rules to be found in circulation today, but because of the vast number of model types and styles of rules manufactured by K&E over the 100 plus years of its existence.
 
**A promise I make that is true since my beginning on eBay back in 1999~ I do not hold items. Once you see the tracking number, the item is taken out of the house to be shipped as I'm first and foremost, excited for you to get your item and secondly, I'm not into clutter. SO, please be patient with our delivery systems as they are overwhelmed and I can certainly speak for our local PO. They're operating on a skeleton crew and UPS also drops everything there for the USPS people to deliver! Thank you for your understanding of this and the fact that I have no control of your item once it leaves my very capable hands. Thank you for perusing our site and God bless~ 

Also, combining shipping doesn't mean you get 2 or 3 items shipped for the price of one as a few have thought lately. It means I will pack everything together and save you money as in this example; one item is $4.15 to ship. Say you want 3 items, it will be less than tripling the price to be $12.45 but they can not all go for $4.15. (o:

Auction items must be paid for within 12 hours or I will need to relist, thank you.

One more thing which I'd like to mention is that when eBay gives you a delivery time, it's only an estimate. Many things can make the shipment late with no fault of the shipper so please remember this and give the sellers feedback based on the item you received, not when you received the item.
