This bass drum 20x14 came with a kit that had two Ludwig Classic toms 12" Snr.1897991 and 14" Snr. 1898469. No date stamps. 6-ply clear maple. So I date them to be late 78-79The bass drum is missing the B/O badge and with bass drum spurs that are rare..drum has Classic lugs + T-rods. Is this a Ludwig classic 6-ply maple 20x14 bass drum ? I am in doubt...
Yes, this is the 6-ply "Classic" maple bass drum! The Ludwig 1984 catalog shows two different sets, with 20x14 bass drums, with the 1/2" L-1308 arc spurs in the same position as those on your bass drum. Ludwig will no longer install these spurs on 20" bass drums. I wanted these spurs on my 20" Classic Maple bass drum back in 2012 and Ludwig would not install them!
Here are the two 1984 sets with the same arc spurs... https://www.vintagedrumguide.com/images/ludwig_sets/1984_ludwig_drumsets27.jpg
