Gruber Wagon Works

Why it's listed
The Gruber Wagon Works is a two-and-a-half-story, T-shaped wooden frame wagon factory in Berks County, Pennsylvania. Its main section was built in 1882, and a 1906 addition housed a painting and drying room and an elevator. Both sections have medium gable roofs with cornices, and the windows are symmetrically placed double-sash units with plain moulding. An oriel was added to the first floor at a rear corner, where the office is located. The interior holds the machinery a wagon maker needed, including one of only two hydraulic rim-shrinking machines in the country. Original wagon makers' benches with vises, a bandsaw, spoke-setting rigs, a spoke-shaving machine, a tire shrinker and bender, and a forge with trip hammer are present. Power comes from a 1906 Otto gasoline engine made in Philadelphia. The factory is regarded as an extremely rare survival of a wagon works, largely unchanged since its construction, and an important record of Pennsylvania German farm wagon production.
Significance in brief: The nomination argues the factory is nearly complete and largely unaltered, with its original building and wagon-making machinery still in place. It describes the site as a rare survival, probably unique in its completeness and integrity, and as a valuable example of Pennsylvania German farm wagon production.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
