Golden Oak Drop Secretary with Glass doors and Mirror

I received this secretary from my grandmother after her passing. Her brothers brought it from Kansas to California for her during the Great Depression. I have 4 wheels for it but only 3 appear to be original or at least the same. The organizer within the desk itself is able to be removed, as shown in the photos. All the drawers have numbers written on them in pencil. I don't have keys for any of the locks, but there is a lever to keep the left glass door closed. Per the partial sticker on the back and the stampe it is "No. 118."  I think the partial sticker also says, " XXX Richmond & Co "The place to buy your furnished goods XXOCKTON, Kansas". I would like to figure out who made it, roughly when and how much it's worth.
