Phil Sharpe talks about the Jordan. It was apparently a very high quality press and one of the first set up for volume reloading. It doesn't use the standard dies we use now. I think it came out in the '30s and may not have been in production after WW II. If it has a built-in powder measure it may be set up for the standard load of 2.8 grs of Bullseye for the 38 Special or may be set up for Pistol 5 or something else. All I know about it is in his 'Complete Guide to Handloading'. An instruction manual for it is going to be very hard to find; people haven't got into collecting old reloading tools or the archeology of reloading.
