The #27 was definitely not written in Fisk's hand.
My friend Tony Swann is the ultimate Fisk collector and has over 60 Fisk game used bats in his collection.
I tossed the knob photo over to him, figuring his opinion may be helpful.
If you have never visited his site on Fisk, check it out. It's AMAZING!
His site is:

I hope this helps.
