Without seeing the original photo, a lack of turnups could indicate wartime production, of course, but reading between thye lines of your description I'd hazard a guess at a 1970s 'Classic' (rahter than 'Fashion') suit. Lovely hat. Interestingly, I think it's the hip hop kids have done a lot to help keep the Homburg alive. I find them a wonderful hat - easily as wearable across a range of dress up / down as a fedora. (Notably, much before the thirties, the Homburg was a much more commonly seen hat across Britain and Ireland than the fedora; the latter gained popularity, likely mostly via Hollywood, from the early 30s onwards, in parallel to the beginning of the hatless trend over here.) They're also a great 'first vintage hat' because they're so widely available and affordable; I have four or five in lovely condition and I've never spent more than about twenty quid on one. Compared to a similar-condition fedora from the same period.... Grey or black, anyhow. Brown and other colours are rare indeed, it seems.
