I believe Dufferin introduced that logo before 2004, although it is the current logo. That pin is brass, and that insert is aluminum. I believe there is evidence for this design series being made between 1998 and 2002, with that bumper as well. Dufferin definitely did make brown phenolic joint collars as well. Although these are not the old "Silver Leaf" cues, if that cue is Canadian, that might actually have ebony points, and it might be full splice. In fact I am aware of a cue from this model series that is definitely full splice with jet black points. Whether it is genuine ebony might be debated.
I am looking for direct evidence but I believe Dufferin officially registered the continuous, underlined script wordmark in the mid-to-late 1990s as part of a major visual rebrand. The goal was to phase out the traditional logos replace them with a sleek look that matched the styling capabilities of their updated Toronto machinery. When the original Canadian operation collapsed in 2004, this specific script mark was part of the primary intellectual property bundle acquired by Cue & Case in 2005. Because they used it globally across all subsequent overseas production lines, it created a false impression online that the script itself originated in China.
To verify this I need to access the the Canadian Intellectual Property Office (CIPO) image logs, which I only just found.
LINK It looks like they only have recent filings, and they are having technical problems, so I am not sure what help this will be. I'll also look for any public filings of the Cue & Case acquisition, which may have some details.
Working on it...
Of course, I could be wrong.
