Probably Philippean or Honduran, as they were typically the two most used then and today. Philippean is more redish brown and softer. Today the Meranti (a plantation grown Philippean look alike "mahogany" ) is used a lot, as true mahogany is harder to get. Meranti is the stuff you see sold as "mahogany decking". Many times Honduran was used on seats, as it is harder furniture grade material....and is more yellowish red.
