The Music Trade Review also reported that about this time they had purchased a vacant block, bounded by East 150th street Exterior Street and River avenue in the Bronx, with the intent of building a new factory but had opted to secure additional quarters instead. Lindeman & Sons were listed at 548 West 23rd street and 155 West 125th street in 1906, and in 1908 only at the W. 23rd street address.
