KlipschSince1981

I don't have a picture of my Klipschorn label but the info from it is: TOP SECTION - KB BLS-MAP HF, Serial HF 881 3865 BOTTOM SECTION - KB BLS-MAP LF, Serial LF 881 3868 My question is on the "BLS-MAP" info. I am assuming it is Birch Lacquer stained in Maple but I can not substantiate that anywhere. Can anyone provide additional information on this? Thanks in advance and I will try to get some pictures on here soon.
