A Wheatstone 46 key Maccann No 23529-which should be around 1900.
It has metal ends and buttons, a riveted action and 5 fold bellows. The odd thing is that it has brass reeds- mind you-these are Wheatstone brass reeds not Lachenal ones and so they are much better.
It looks very nice and plays well but is more gentle than it would have been with steel reeds. It would make a great instrument for a talented learner.
Comes in its original hard case which is not in great condition but could be exchanged for a new gig bag.
