[Boatanchors] B&W 425 LPF?

[John Flood]

Greetings,
Just going through a box o' stuff from the estate of a friend who passed away a while ago and came across an older B&W 435 52 Ohm LPF.  This one has S/N 101 stamped on the lable and it got me to wunderin'.  Anyone have an older one?  Or <insert fantasy here> they started at s/n 101 and I have the first one and will make millions selling it...  <back to reality> It looks beefy inside will it handle the output power from my Johnson Viking Valiant without dammage?
