It looks like a huge and very angry anus.

I like 70's retro, and am very tempted by the Luxman kit on ebay at the mo':

1920's is a bit early for me, although a bit of nouveau stylee is never a bad thing.

Edit: Actually, the more I look at that horn, the better it looks, and not because it reminds me of an anus, ha ha.....and having looked at the original post where it mentioned 'retro reproduction' the whole anus thing is becoming more and more inappropriate.

It looks very.....er....nice.
