You're forgetting the Leica part, which could be pronounced licka. I can neither confirm or deny that but in theory, that would give you licka...nevermind. I don't want to get kicked out!!!
That's a big negtory, windsorguy. In German, when vowels come in pairs, it almost always the second vowel that gets pronounced in the long form. Ergo, Leica = like-a.
