This drum is definitely a 1920s Ludwig & Ludwig gold plated /engraved Triumphal Model. I did notice a few minor differences as compared to my Triumphal... 1. This drum has a 5-petal rose engraving as compared to my drum that has a 6-petal rose engraving... 2. This drum has the “Ludwig Chicago” in the same panel as the P-338 strainer as compared to my drum where the “Ludwig Chicago” is located 2 panels to the left of the strainer. Nothing earth shattering but interesting enough for me to pursue it further, ergo; was this a different engraver than my drum?
