Take it to LBS and say 'I need QR skewers please'. Job done.

I thought that you could get QRs for just about everything nowadays. Heigh ho, I stand corrected.Good luck getting QRs through that solid axle....
My favorite set of spanners, they can grab anything15mm as above - I carry one of these mine. It does the job and is small enough to be convenient to carry about - http://www.ebay.co.uk/itm/Yato-Prof...t=LH_DefaultDomain_3&var=&hash=item3ced74e178
