Need a bottle of each, any kind. See moved thread below for story : http://beeradvocate.com/community/threads/iso-wellington-pump-house-beer.142336/
I have my own bottle cap collection as you can see bellow http://i402.photobucket.com/albums/pp105/City_of_Doors/200Bottles_zps2de79bcf.jpg and Wellington used to use the caps you see in the top left hand corner. However, since they've switched their branding from the Iron Duke to the Welly Boot, I honestly don't know if they've turned to generic caps or if they have Welly boot caps. I'll see about picking up a six and finding out.
Sorry can't help. No one is taking my Wellington 'Iron Duke' baseball cap from me. Ever. Just wanted to say that.
