Is there anyone who know what differentiates the PW4052, PW4056, PW4060, PW4062, PW4062A, PW4152, PW4156A, PW4156, PW4158, PW4460, PW4462 from each other? If they are all based on the PW4000-94, there must be some small to moderate differences in each of them to justify issuing them a separate model number, but what are those differences? I could find no literature explains the differences between the aforementioned models.
Anyone who knows what the differences are, or knows a website which explains the differences between them, please let me know.
Thanks to all who respond.
