If you have an older copy of Joy of Cooking, would you look for a recipe for me?

My mother had a Joy of Cooking from the 40’s. In it was a brownie recipe – I think it was called “Brownies II”. The brownies were a family favorite and I would like to make them for my father’s 90th birthday. If you have the recipe, would you be so kind as to give it to me?

I remember it called for lots of eggs (4?), unsweetened chocolate squares, and required a larger than 9 X 9 pan.

Thank you!
