Kerrville's Griner and Grona Blacksmith Shop

Griner and Grona Blacksmith Shop, Kerrville, in the 800 block of Water Street.
This photo was probably taken around the turn of the last century.

Recently some friends brought by a series of very rare images, including this one.  Max Grona is standing in the doorway, and it looks like he's heating a steel rim for a wagon wheel in the foreground.  I think they'd heat up the rim so it would expand, then place it on the wooden rim and wheel, then rapidly cool the rim down, so it would contract. 
I think this blacksmith shop was in the 800 block of Water Street, opposite, roughly, where Francisco's Restaurant is today, and near where the old Blue Bonnet Hotel once stood.
If any of you have a better memory where this blacksmith shop stood, please let me know in the comments section below.
