It looks like it could be a duckbill.
But it's a side on view that would give the definite answer.
It is an older example looking at the direction of the milling marks on the table and that fits with the brass cap and ligature.
The offset M appears through out various era's but that makes it more sought after by some people.
Thanks all. I attach a side view. By the way, I tried a modern bronze Berg tenor recently and a/ the mp seemed too narrow for the reed b/ it only went about 1 cm onto the crook to play in tune. Is it just me or have they gone downhill?
It looks like a Duckbill to me but i might be wrong, see what the experts say. About the quality.. some reckon they have gone down the nick, others seem to like them. My straightbill from the nineties is a great piece, that was made in the UK and the reed fits the table perfectly. The latest ones are made in Belgium as far as i know, so they could be cutting corners! who knows.
