How to identify replacement key blanks for old padlocks

[Pschiffe]

0997E blank would work,a 4 pin cut on a 6 pin blank
z=j or 10 series codes

Cuts 7674 on 0997E Ilco or equivalent. Interestingly, the old Reed Padlock Cook Book, pg. 02-Y136; notes that it is a 4-pin code used on a 6-pin blank (12-1/2) with the first two spaces left un-cut! This explains the apparent discrepancy in the catalog description of this padlock which I noted earlier. Thus spaces used are 3=.430, 4=.570, 5=.710 & 6=.850 while depths are 4=.196, 6=.160, 7=.142 per Blackhawk Codes on Line.
