The renting agent calls attention to the \\s 
Wolff Plumbing Fixtures as his best guaran- ANS 
tee to the prospective tenant of the high grade Bee - 
of the plumbing system—indeed the type of the \\\ 
whole building is many times inferred from the AS 
use of Wolff material throughout. ) 
When renters become builders the worries from 
‘assembled ’’ plumbing contrasted with the perfect ser- 
vice of the all-built-by-one-house Wolff plumbing makes 
it easy for the architect to use Wolff specifications.
