Antique 3-Track Cast-Iron Cribbage Board: Please Help ID Age & Maker

The upper surface is 11 5/16" long by 2 1/4" wide; weight is 12 5/8 oz. It seems to have been polished an' perhaps even plated (pics 2 & 4) at one time, although there is no evidence of plating on other surfaces. The feet are ground, so it sits dead-flat. The peg holes are ~1/8" diameter on the top, tapering to ~3/32" on the back...there were no pegs with it when I got it ~40 years ago.
I'm about to give it to my daughter, who has just begun playing cribbage; I no longer do, so have no further need. I've tried Google images in hopes of finding one like it, but without success.
Can any of you offer clues as to where, when, an' by whom it was produced? I'll be most grateful for all your comments, an' thank you for lookin'!

 

I've found that there is a Cribbage Board Collectors Society group on FB...but I'm not a FB member.

 

It doubles as a trivet for the Cribbage enthusiast!

 

I was thinking grater.

 

FB can be very useful, but you wanna create a foolproof alias/phony identity-who needs odd bits of our past poppin' in ?
Re-The Cribbage piece,I assume you've scoured it visually for teensy Patent #'s/dates ?

 

Nah...the holes aren't sharp on the edges because they were cast-in! All other features show the same sophistication in the apparent 2-part mold...this is not crudely done at all.

 

Like everyone else, I signed up to FB early...an' spent an unduly miserable amount of time extracting myself from Zuckerberg's steely clutches...Never Again!

Correct, Bosko...every surface has had sharp inspection under the 10X loupe...Nada!

 

Not everyone.

I signed up a few years ago, only to follow Monash Uni updates about the diet for my IBD.

 

Ditto-Use of FB judiciously can connect you with some actual experts, course you've got to exercise critical judgement in figuring who's dispensing actual curated science and who's bloviating.
