I was looking on eBay for a cheap 1/16th 1/10th violin for my 4 year old granddaughter.
I added one to my "watch list" and then noticed this. Although described as being in "good condition" the f-hole is mouse chewed.
It is being sold (supposedly) by the children's charity Barnardo's. Am I right in believing mice do this in order to nest inside violins? If so, maybe they are marketing the violin as a hole. Ahem! Sorry - Freudian slip typo. I meant ...as a whole...in "good condition" for a mouse? They do say the violin shows "signs of use" - so that hypothesis is not disconfirmed if they are marketing it at mice rather than humans.
