Soon the Kollmorgen buildings on King Street, including the navy grey tower that once housed the calibration equipment for periscopes, may fall to the wrecker's ball. Today Kollmorgen Optical sold its 5.1 acre parcel on King Street for $1.8 million to Tommy Car Management Corp dba Cozenzi Automotive, owner of Country Nissan in Hadley, and Northampton VW on Damon Road. The price is substantially less than the $3.07 million value placed on the parcel by the city, and may reflect the cost of cleaning and demolishing the buildings. Patrick Goggins, who represented the seller said both the deep discount and the delays in closing on the sale reflected the time the new owners had to devote to so-called "due diligence." It was a factory and machine shop since before World War II, and disposal of solvents and industrial waste was haphazard in those days. The new owners, Carla and Tommy Cozensi, the partners in Cozensi Automotive, have not returned our calls at this point. A realtor we talked to said that Northampton VW on Damon Road is doing well, but needs more room to display cars. He had heard that the Cozensis plan to demolish the buildings on the site, As of this afternoon, no permits had been applied for at the Planning and Development office.
