Hi Rob, I can't see any real difference between the two except that Alan's uses some more modern components - for example, at the top of your picture is what looks like an OCxx transistor which, in Alan's, has been replaced by a metal canned type. There are also some differences in the style of some of the components, like the two ceramic capacitors between the tuning capacitor and and the switch.
The only real difference that I can see is the red wire link along the bottom of the board on your's - toward the right.
However, as Alan's PCB looks to be a revised version of your's, I would guess that the opportunity was taken to add the missing track in place of the link.
