I have two, a PN-4A and a PN-5. The 5 was in the box of other items for the Silverado, but I also found the 4 in my cabinet with a painted silver finish. Seems to match, so I wondered is that the correct PN?
David is correct. I have a Silverado gray PN4A paired up with one of my 1205s but the PN5 also shipped with the Silverado. There was also a brown version of the PN4/4Afor the Olympia. For both aesthetics and performance, I'd go with the color coordinated PN4A
