Just before you click through to the catalogue its worth pointing out that there have been (and might still be) a few errors in the new catalogue.
I wish I could point the finger at someone else, but no, its my fault.
There were several driving wheels missing from the list and worst of all I mis-typed the PO Box number in the address.
Please make sure your using
PO Box 597, Oldham. OL1 9FQ.
