small pin tumbler push key padlocks

[nathanbonstein]

need help with the ilco GN and R dsd codes for a couple of these ilco padlocks ? would greatly appreciate the help.
one of the ilco a lockwood blank marked 1004B fit,a y52 would not quite fit ,it is probably no longer available. the y52 even fit the corbin keyway.

These are some nice padlocks Donnie, i can return the finished ones or wait and return all at once ,let me know,your choice?
thank you
