Technical Year ID help please

Okay... I picked up this Nodular housing at the Turkey Rod Run Swap Meet the other day...
Not that its if significant importance.. but I was just trying to ID the year of this unit.
I know the number before the F30 will ID the year.. but cant seem to make a number out of this...
I know the 2 dots above/below a number is either a 6 or 9... but this number looks like neither...
Any help would be appreciated...
thanks guys...

I wonder if the foundry workers had any idea that stuff like this would matter, 50 years later?

it sure looks like a 3, doesn't it

the date on the pinion support..is it close to the date on the case? matched set?

 

Im talking about the number directly before the F30

I know. It looks more like 3 than any other number, to me.

But can clearly read a 9

Upside down 2?

 

my first thought was a 5, stamped using an imprint stamp, instead of a reverse stamp like the others. new guy grabbed the wrong stamp?

 

Don't know about the 2 dots under it. but it sure looks like an inverted 2 ?

 

It looks like an upside down 2 also... but doesnt really help me date code it... [emoji37]
