Hello Anthony, thats a very nice pot you have there. You say its a 36 quart, thats nine gallons, but it is marked a number 10. Have I got that right?
If so, I think it would be for use in the home. Its small enough to fit in the hearth, but yet big enough to cook a nice batch of something in, or maybe cook a nice hogs head in, with all the trimmings, or maybe boil water to bath with.
But on the other hand its not really big enough to do much with outside. By that I mean you can't scald a hog in it, you can't boil enough water in it to scald a hog, you maybe could if you had three or four of them working in tandum, but by itself no. And as for rendering lard, MAYBE one small pig, MAYBE. But as plentiful as the larger pots were, you would just not use one like this for outside. So I think its for use inside.
And again, I think its a very nice pot. ;) And yes, I mean NO, no hole drilling.
I have told this story before. There was a seller that had a number 13 Griswold Dutch Oven, and they had the nice cover with it and all, and they were bragging how it was already drilled with holes, and you probably didn't want the lid but they would send it along if one wanted it. And they were pleased and proud of that. Kind of a convenience thing, "predrilled". Made me want to reach through the computer and slap somebody. ;D
