Vintage MONROE Adding -Calculator Model LA-5 With Case, keys, & Instructions

Description

This is a vintage MONROE Adding-Calculator Model LA-5 in the case with a MONROE cover.  It is old. Cord is there, extra turner thing that I don’t know where it goes.  Has been on a shelf in the garage for years safely tucked away.  Case has musty order when opened.  I would put it out in the sun?
We are assuming it is a model LA-5 as that is what the little paper instruction booklet has on it.  You guys out there know more than we do, so let us know if we are not right.
From non smoking no pet home.
Has the case, cover, instruction booklet, keys, and cord.
Please look at the photos and ask questions before you bid as this MONROE LA-5 is NOT returnable.
Shipping is priority, insured, with tracking numbers.
