How rare is a Prestolite distributor?

[resq302]

I was going through my box of parts in my basement trying to thin out my junk (ok, its technically not junk but one mans junk is another mans treasure) and I came across a Prestolite distributor with that odd looking vacuum advance on it.  I really have not seen any like this on other Mopars at shows yet the factory service manual says they were on 383-4 bbl manual and automatics as well as the 440-4 bbls.  The distributor appears to be in really good shape and still retains a tan cap and looks to have a fairly new set of points and condensor in it.  How much are these Prestolite distributors worth?  I will try and take a picture of it tomorrow.

Brian,

Tony D'Agostino has a slew of Dual Points listed for sale on his website.  They range in price anywhere from $75 up to a max of $295.  Probably depends on their condition, the specific model you have, and perhaps the date code that is on the metal tag.  If that vacuum advance is in good shape and functional, those are valuable since the supply of NOS advances has pretty much dried up.  The metal part of the advance unit can't be replated because of the rubber diaphragm.
