If you don't have any luck figuring it out for certain and you
really want to know I can put you in touch with my sister and she could tell you if you send her your pics. She has a BSc in forestry, Masters degree and went back to school to get her doctorate. She's a bit wacky though...very preachy, extreme environmentalist and we don't keep in close contact. You might want to use her as a last resort
