Im gonna have to look for this beer and give it a shot .
A recent post by historian, Ron Pattinson about Boddington's output in 1939 (he's on a World War and inter-war kick at the moment) shows they made a couple of mild ales... a pale ale... a stout and a strong ale. Other records show they also quite often made an IPA and I even remember seeing a brown ale once.
Here is a bitter derived from the Boddington brewery records in 1971 (that's about a contemporary as Ron gets).

The problem is this: If the US Boddingtons is what she likes, then it makes sense to try to recreate that...no?
I have not had the real deal, but I enjoy the US version...just had a can last weekend. I'm on a mission to go on a UK pub tour....it will happen within the next 12 months.
That being said, there's some great advice in this post. The first thing that popped into my head was to keg condition the beer. I think you get a creamier head that way.
My sister in law (who this is being crafted for), would have enjoyed this while living in the UK in the early 2000s if that helps me narrow it down a bit.
