Looking for advice on this set.

Bass drum is a 20x14 Rogers Mercury. It is complete with all original smooth large bead and butter lugs and long, single-tension rods and claws. Virgin bass. It has no extra holes and no badge or label.

Floor tom is a 14x14 Slingerland dated Feb 65 "M". Looks to be complete and all original including COB hoops, tone control, lugs, rods,legs, and push-button leg mounts.

Small tom is a 12x8 Rogers with only one original lug (large b+b). It doesn't have a badge or any extra holes. Does have the original hoops and tension rods.

Snare is a 6 lug Rogers. No badge. Only three lugs are original (small smooth b+b). Extra holes were drilled for some new lugs and for a different strainer. I have the original strainer. (I did not drill the holes. These drums are exactly as I found them.) Also has the original snare stand. I have some of the broken b+b lugs and inserts and springs.

What would be a fair asking price in this condition? Should I sell the pieces separately or as a set? Thanks for looking.
