Anglo Aeola concertina by Wheatstone in C/G with 40 keys including a drone button giving C in both directions plus an air button. The instrument is tuned to A440 with 8 fold bellows supplied with a lined hard case. The righthand frame is stamped R 7a, indicating that this is a model 7a, i.e. Aeola. Wheatstone sales ledger SD04 confirms that this is a 7a, and gives a sale date of 8 April 1972.
The bellows bear an internal label "Vervaadig dear: Wimpie croukamp 012 3794601" and an inscription 1/4/0003. This may be Dutch or Afrikaans. This label may confirm that the bellows have been replaced at some time, as possibly implied by the bellows being 8 fold rather than 6.

Reason for sale - too complicated for my small brain! I ams also selling a bass viol, tenor shawm and a quartet of cornamusen (if I am permitted to mention these).
I am in the north-west of England if anyone wishes to "try before you buy".
I will to course make a donation to concertina.net in the event that the ultimate buyer first learnt about the instrument on this site. I should have listed this instrument on this site first, but I have already listed it on Ebay.
