This 5x14 rocket lug snare I won on feebay came in today. Had the same throw off/butt combo as the Rogers war model in the early Rogers history web page here. I thought it was a Newton model 5x14. The Rogers catalog shows the Newton with the english copy of the Leedy presto 2pt. It was bugging me so I checked the 38 catalog again and found this small throw off on the Manville model.
We have been calling it a Leedy Utility throw off. Nope. It is a Duplex! Checked Harry Canganys Great American Drum book. He shows a picture of it under the Duplex section on a Spirit of St. Louis model and lists it as the throw used on Rogers Manville too. Thanks Harry! Now we know and can correct it on the web page here. Also this confirms that the rocket lug snare that arrived today is a Rogers Newton Model. Peace, Gary
