For future reference Imperial confirmed for me that L28 Urkel is 2278. Mr Malty says that's Pilsner Urquell strain D.
WY2001/WLP800 is Urquell H strain, the one used alone since c.1990.

I'm not doubting you (well - kinda surprised that of their 5 strains they chose the ale one) but it's always good to know where these equivalences came from.
