Mid 80's like you mentioned is correct.

Mike

Thanks Mike, any idea on a ballpark value for this age? To complicate matters I have a retrofit 'Trick' throw off to replace the P-85 (although I still have the original strainer).

Just a point of clarification, those are imperial lugs. There were some Supras fitted with bow tie lugs, such as you'd see on an Acro.

Regarding value, I think you could expect $300 at the most. It's in good condition but nowhere near mint, and '80s drums aren't as in demand as those from the '70s.

The Trick throw off wouldn't increase the value in my mind. Most buyers would likely prefer the original throw off.

You can also look at completed eBay listings for similar drums to get a more accurate price point.

That particular badge pinpoints the year to 1984(ish) when Ludwig brought the keystone badge design back (albeit a larger version) most likely in connection with their 75th anniversary which was that year. The next year they moved out of Chicago so the "Chicago large Keystone" was only used around that relatively short time frame (the badge design remained in use but the location at the bottom was changed to Monroe).

As mentioned those are "Imperial" lugs which were standard issue on that model (402 Supra Phonic). Interestingly though, some drums from that year did use the "classic" bowtie lugs in place of the normal Imperials. It is theorized that near the end of production in Chicago they ran out of Imperials and chose not to order more because of the impending move. Whatever the reason it wouldn't be out of the question to see a drum like that, with that particular badge, having bowties from the factory.

I happen to have a snare identical to yours. I also have a hammered Bronze snare with that same badge. I like that they were both made in Chicago (at the North Damen Ave. plant, a place I was fortunate enough to tour in the mid 70's) and were among the last drums to be made there (although I'm sure they cranked out a LOT of drums in 1984, Ludwig was still booming then).

Sooo, it's kind of special although not in a way that probably translates into being worth a lot more than other 402 snares of the era. Many potential buyers are probably going to want an older one with the B/O badge since that has a Bonham connotation...although other than the badge the drums are the same. It might be worth a bit more to some buyers than a similar Monroe badged example due to the Chicago connection.
