       Please note that I will be away from my business travelling from December 14 until March 30, 2013.  Parts orders will be processed although not as quickly as usual.  I will always be available for contact by E-mail.  If you phone your call will be addressed by Stewart Ferguson here and he will either call you back or advise you to contact me directly by E-mail. Details of this adventure are on our Travel Blog: http://frankcondelli.com/travels/
