Unusual Vintage US Navy Stadimeter Box with Stadimeter Frame WWI(?)

Description

This is an unusual stadimeter box.  It is different from the WWII vintage Schick stadimeters that are frequently listed for sale on eBay.  It's also different from the much rarer K&E stadimeters of WWI vintage. I'm guessing it's from WWI or possibly earlier but I don't really know.
There are obvious repairs or modifications including a lighter wood patch that may have covered a missing plaque, and two filled holes in the front of the lid.  Both are obvious in the photos.  Also obvious is a large chip in the back corner of the lid.  The interior seems to be complete.  The green felt shows wear and a few stains.
The box was acquired with the included stadimeter frame and arm.  It seems to fit but I don't know if it's original to the box.  Neither the box nor the stadimeter has any identifying marks.
Check out the photos and don't hesitate to ask questions.
I offer several shipping options.  Be sure to check all options to see which is most cost effective for your location.
