Jacks for Wood-Brooks 90 degree action

[sdpianotech at itctel.com]

Came upon a console in a nursing home with Wood-Brooks 90-degree  
action.  It needs a couple of jacks (among other things - like a can  
of gasoline and a match).  Anyone know of a source for such jacks?  A  
bit longer than standard vertical jacks, with a flared top where it  
contacts the butt leather, and the let off regulating button is  
located in the heel of the jack.  Any help would be appreciated.
