If my research is correct, there is only 3-4 O numbers for this year?
I wish.

There are 23 varieties for the year, using two different sizes of zero in the date. Yours looks like the smaller, more common version, listing 18 Overtons. 1830 is one of the tougher years to attribute - differences are tiny, requiring exacting detail of the relationships between certain features. I came up empty-handed on my first run through the varieties; sometimes it takes a few trips through the book to attribute one of these.
No biggie. I'm a night-shifter and just got up. I'll be awake all night.
