Since exchange rates vary over time I thought I'd better look up Jan 1997's rates as that is when I have the DM pricelist. I managed to find the historical rates between the DM and GBP and also the Euro and GBP which gave me over 20 data points each for Jan 1997. Taking the average for the month for each and then sticking them together we actually get the same rate of 1 Euro = 1.96 DM.
I'll add some suitable commentary to the pricelist page.
