I'm looking for a picture of Business car #3 also know as Meadowlark from it's SP days.
Not sure this will help, but there is a picture of New Haven Business Car #2 on page 531 of "New Haven Power 1838-1968" by J. W. Swanberg. I do find photos of business cars #1, #2 and #4 in other New Haven Railroad references, but nothing on #3.
Upon further checking on the website of the New Haven Railroad Historical and Technical Association nhrhta.org, Volume 26 Issues 1 and 2 (1995) of "Shoreliner," the Association's quarterly publication, have articles containing a total of 27 pages about the history of New Haven's business cars. From the main page of the website, select "What has been published in "Shoreliner," then select "Passenger Cars" and look under Volume 26. Then look at the "contacts" page for whom to contact. These articles will probably be the best information available. Sorry, but I don't have them.
