WIW: Various cores, dated vs non-dated

[CudaJim]

Going through the stash, thinking about vending at a swap meet - any general thoughts on dated vs non dated parts, particularly on 'cores', as follows:

BB water pump housings
Starters
Alternators
Power steering pumps

Some not particularly valuable, and some likely too heavy and too common to make shipping worthwhile (or even to make hauling to the swap, and likely back home worthwhile). but I don't want to just toss any either... thanks for your opinions
