Featured Age of bird’s eye maple dough bowl?

This was my find today at a local thrift store. It’s huge! Slightly off round, it measures 17 inches in diameter in one direction and 16 inches in diameter in another. It’s a bit over 5 inches tall and slightly asymmetrical in height. There is a 2” rim crack. It looks a bit dark because I’ve just given it a go over with food-grade mineral oil. (It was dry and dusty when I bought it.) Also, I'm taking quickie photos in a not-so-well lit room.
I have seen large round bowls such as this referred to as dough bowls, as well as the elongated “trenchers”. I have also seen these old large bowls referred to as chopping bowls. This one does have some knife marks on the inside bottom of the bowl (see last photo).
So… Is it a dough bowl? Any guesses as to age? Thanks so much!
(I’m so excited, I love it!)

Edit: more photos taken in natural light in post below.

 

I LOVE IT!!! <3 LUCKY YOU!!! <3

 

The crack and oval shape are a condition of turning green wood... https://www.finewoodworking.com/2008/09/03/green-turned-bowls-working-with-warp . Hard to tell the age,could be 30 years or 60 years,etc.

 

Beautiful!

 

Thank you!
Most that I see online claim to be about 100 years old. Naturally, I was hoping this one was, too! No turning marks but I suppose those could have been sanded away? Here are some better photos in natural light:

 

Not A Clue! but i like the birdseye maple! very nice bowl. I think it being out of round is a good thing (sign of age due to shrinkage) but i really don't know that for a fact.

 

Very nice bowl, Bluumz!

 

Thanks! I've been reading that being out of round indicates age... but how much age, I don't know.
I live in Michigan and there was a company in Munising, MI that made bowls as well as other wooden products, from 1911-55. Munising (pronounced MEW-niss-ing) often worked in bird's eye maple and the earliest bowls (1910s) were not marked. However, I can't find any of their examples that had a rim as mine does.

Edit: I just found a smaller Munising bowl with a rim here! It has the straight block lettering brand that the company used in the 1920s when they first started marking their items. A slanted script brand was used from approximately mid-30s. I suppose I'll never be sure, but it does seem possible that my bowl could be a 1910s Munising bowl, or possibly by its predecessor in Kalkaska, MI, the Freeman Manufacturing Co.

 

Wow!!! Gorgeous

 

I think that's right as you are in Mich. I don't think there being no tool/lathe marks is that big a deal, birdseye maple tends to be very hard and finishes/polishes to an almost stone like surface plus i would guess birdseye would most likely be a deluxe model of bowl, leading to extra care when being made.
