Could be one of three series, The first one the last version of the ludwig Standard 1982 unimold 4 ply shells,second Ludwig S/L,this series had a 6 ply kick with 4 ply toms,third early Rockers.All three series had mini classic lugs on toms,large classic lugs on BD.All three came in red.I believe early rockers had granitone interiors.
I have an S/l kit and it also has the beige/yellowish paint on the interiors,not all do,between my kit and the 8 or so others I have seen on the net they all have a 6 ply kick,but more than half differed from mine because of different BD spurs,and some of the badges had serial numbers,most did not as far as I can tell.Your spurs are the same that came on the Ludwig standards.
