Big Boy Stihl 088 Bar ID assistance needed

[RJPassmann]

Hi all, I picked up this vintage Oregon Bar for my Stihl 088 today and need help identifying it and what chain I need. Seller said it has been hanging for 20 years, still has paint on the rails! Does anyone know how to interpret the etching, shown in the photo? . I have a 404 sprocket on the saw, the tip is a 3/8 though. Im not sure if it is 0.063, the seller showed me a “72” chain fit the slot, but it did have a little slot.

Looks to have originally been a .404 bar that's had a 3/8 nose fitted. That will mean you need to run 3/8 chain & it will change the drive link count.
It will most likely be .063 but I'd measure the bar groove to confirm

423- - - E031
42"
.063 guage
Then bar mount E031
There's 3 numbers after the inches on Oregon bars ; 0= .050
8= .580
3= .063
Obviously the sprocket nose has been swapped.

IMO, 42” on up should be .063g .404.
safety reasons…

Doug Dent’s book was my first back in the 80s…made an impression

Thanks Gents! That tells all but the length of chain, which i can mock up to figure out. For $100 I at least have a decent bar to show the saw. What are these worth?
