Can you ID these Vintage Racks?
 

I have a couple of vintage racks I need help identifying and dating. One is a front rack, the other a rear, both of which mount using the brake mounting bolts. Rear rack is certainly a Blackburn, I'm assuming front is as well.

What I'd like to know is approximate age of the racks. A catalog scan would be perfect.

The front appears to be a Jim Blackburn rack as well. I can read "Jim Blackburn" on the rear rack. The early racks (up until the late 70s?) included his full name, and then later "Jim" was dropped. The front racks are less common (read: more valuable). I think you will find "Jim Blackburn" printed near where the front rack attaches to the fork.
