Alternative Keywork

Alternative Keywork Name	Makers who Used / Years	Pics / Notes
	Buffet Elite (pics taken from German eBay) Special keywork. Notice the “open” hole just above the bell. And the extra keywork from the top of the register key going all the way down the lower joint	If you look closely there an open hole on the left as a vent Take a close look at the register key, the pad cup. It activates a long actuating arm which has it’s own bridge and continues to the lower part of the lower joint. You can see the rod keywork alongside the bottom of the lower joint. It ends and the padcup goes along the backside.
Mazzeo	Selmer / mid 1960s Each model, Selmer Paris, Signet and Bundy had slightly different features.

The first picture has a Bundy Mazzeo (on the bottom) and a Signet Mazzeo (on the top) The Signet mechanism (left) shows it in the Mazzeo position. It has a knurled end “plunger” mechanism to turn the Mazzeo system on/off. To disconnect you simply push the mechanism in. To reconnect you pull it out.

Keywork Modifications

Eaton International

Here is some excellent work from Chris Peryagh from the UK
as he adds a Ab/Eb key to an Eaton International. This work does not
modify any posts or anything and the original lever can be reinstalled to
eliminate this modification and keep the instrument close to original.
SN398

ok, an oboe, but great keywork modification
