Bump.

Anyone have any info? Please? :-)

I love that blue wrap !!

Have you used the drum guide ??

Thanks Oddball! My original post was on 8/11, so I thought I'd do the "bump" to see if it would generate replies.

The drum guide shows Blue Onyx wrap as late as 1973 (better info than the Rogers book I used), but still doesn't say when the "D" was dropped from the strainer or give a better idea of serial number dating. I know they stopped making wood Dynasonics sometime in the 70s.

And still searching for info on this Big R model.

I just did a quicky look for ya and from left to right, the Big R badge then muffler knob, then throw-off, in that order -1983 !!

Look at the photo of the 83 snares, you`ll see yours !! (in our guide)

The Big R 70xxxx is 1977. Solid data for dating that one.

1975, five digit numbers to about 15000. Badge on right side of throw off, covers oval badge screw holes. These are the first gen transition Big R drums.

1975/6, five digit numbers into the 40,000 range, maybe higher. Badge moves to new Big R location, two panels to the left of the throw off. No Dampener on most drums.

1976, six digit numbers starting in the 60xxxx range.

The Blue Onyx is offered in the 1968 catalogue and pictured in the later 68 flyer. I believe your number puts it at a very late Dayton or very early Fullerton. It is in that time period, Im not sure. Others are more precise on these dates.

I am the go to guy on the Big R dates.

Thank you both!

Any idea of when the dynasonic frame (see photo in my first post above) dates from? My guess is "later" rather than "earlier" since the ends are flat.
