jig identification

[Pat]

Can anybody help me identify a jig that I have had for more than 25 years, I need some guidance on how best to use it. It consists 2 pairs of rods, one approx 8mm dia and the other 10mm with a flat for a grubscrew, they are 18 inches long. There are several aluminium blocks drilled at right angles to take the rods with a grub screw to secure the larger dia rod. There is a nylon fence approx 1m long with a groove to take an aluminium bar approx 9 inches long. There is a pair of blocks 3inx3/4inx10mm (excuse the mixed systems) with two holes to take each rod and a thumbscrew to lock the adjustment.

It's his first post; needs three I think to put up snaps...

Thank you ,both, but I did not think a picture of 4 rods would help much.

Yes, but the interesting bit is the blocks and fence?
