This may or may not work for those of you heading for Poland this year, I'm surprised at how many of you there apparently are. There is a very good E-Bay seller of vintage bike stuff in Poland and perhaps he might have some suggestions for you or even show you about a bit if you enquire nicely. His contact info is :
Bartlomiej Prochal His E-Mail is zygibajt@wp.pl Slusarska 3 53-207 Wroclaw Poland
I have dealt with him a couple of times and he is most trustworthy and one of the cleverest folks at packing a bike that I have ever seen. Say "Hi" to him for me if you contact him.
