Here's a web-site reference to a newly formed shop/vintage club in Germany, http://www. kettenlinie-coeln.de For those not familiar with German, click on the "raeder" link for some nice photos of the members bikes. Although some are not on topic, many are, and there are some very nice Pogliaghi period bikes, among others. The shop also may be a source for some vintage parts.
