Frederick Post Co 1452W Slide Rule.  The glass on the front is cracked, so you might want this for parts.  It is still readable, but, it is cracked.   Please email for close ups.  Other than the cracked glass, it is in excellent conditon, not warped, the little clear plastic bits on the back side are present and have minimal wear (very readable).  Slides easily.  Clean.  This is a nice bamboo slide rule.  Made in Japan. 
Comes with a nice Post leather case.  Case has a few scuffs, one on front bottom, corners a bit bumped, a name written on inside flap.  Was it yours?  Free shipping if you guess the name inside :)  Otherwise, shipping will be $3 in the US.  
I don't know a lot about slide rules, so please let me know if I've left something out.  Reasonable offers considered. 
From my non smoking home.
