hi , i ran across an old business card from Irlbacker &Sons
from 1899.
It lists John, Geo. L, Jacob C, and Edw. F. Irlbacker
address 529 ,531 and 533 Main St. and 504,506 and 508
Washington St. Buffalo, N.Y.
must have been a big operation. I think they built the coppers for my relatives brewery in Albany N.Y.
The Dobler Brewery. It's a nice piece of history from your family, send me an email address and I'll send you a copy.
