I have a ludwig 1983 S/L kit that is very similar,same color,same heavy spurs mini classic lugs on toms, the Bass drum had large classic lugs, same tom mount.
Welcome to the forum by the way.
Where in the world are those drums?
What is throwing me is that badge,I think I have seen it before,but I am associating it with later offshore product.
The S/L kit I had had biege colored paint on the inside.Yours,at least the Bass has a natural interior,which was offered on some rocker drums,but not the ones with classic lugs as far as I know.The grey and black granitone int was on rockers but the later Taiwanese ones had the brown speckled interior.
Rockers had 4 ply shells, S/L had 4 ply toms 6 ply kicks,if the rest of your drums have clear interiors and are six ply that would indicate top of the line Classic shells.

As far as worth goes the snare is worth something for sure,Blue and olive badge 6.5 supras would normally bring 275.00 to 425.oo here depending on condition especially on how pitted the chrome is,yours looks very nice.I have heard 6.5 supras have been going for higher prices lately though.
What the other drums are worth depends on a couple of things,firstly what your local market for Ludwig products is.Those would hard to get more than 400.00 here because of the badge issue IMO.
