yep. You're probably looking at spray foam with a house that old.

Also as an aside: For all those who get spray foam quotes, I can tell you what the material costs. We are currently using Bayer SPF which seems to look pretty good on paper in regards to R Value and so on. We pay $ .50 per board foot. Open cell for air sealing only (R Value of about 4.something) is $ .11 a board foot.
