You are so much smarter than me. I do similar to you, except with Italian bikes, bits & bobs and publications. But I don't speak Italian.
I think 1960s Italian racing bikes attracted me before the British, and language was a big reason why I crept over - that plus the accessibility to knowledge about obscure builders and component manufacturers via websites such as Classic Lightweights. After absorbing most of that information I had to turn to the original publications, which really is quite fun!
