National home closet door roller

A quick learner from Indiana says:
How about a National Home built in the 1950s with 8ft tall steel bypass doors! Some offset- maybe 1/4 or 3/8?
Will need 8 rollers (4 pair) if we can find the correct fit.

Hello! You weren't kidding, this is some old roller. We don't have anything exactly like it but I'm reminded of our 23-067 . This has a 1/4" offset and a wheel diameter of 1". Could you use this as a replacement?
