It just might be that the screw at the back of the check block secure it in place. More than likely, there is a pin registering the front of the block which is exceedingly tight. Remove the rear screw, remove the key slip, get a blade under the front and try the ease the block upwards. Did I mention that the pin grip might be tight? There probably is not a screw going up into the front hidden by the leg mount but don't discount that. To quote a jazz legend... One never knows, do one. -- Regards, Jon Page
