WANTED: Merrimack Railroad History Information

I am writing a chapter on Railroad in Merrimack for the Merrimack Historical Society's second volume of the town's history.

There were three operating railroads: B&M, originally the Concord and Nashua, Nashua and Wilton and Manchester and Milford.  There was also a "paper" railroad the Souhegan that sprung up in the 1940's.

I am looking for any MERRIMACK ONLY related information that current or former residents or collectors might have regarding railroads in Merrimack. I would appreciate access to photos, paper information, post cards, track plans, invoices, way bills, employee information and records, businesses and industries served, etc.  Any doubts/questions, give me a call or shoot me an email.

Looking forward to hearing from you.
