Thanks Alan, I will have to ask Daren, to clean up my mess here LOL. I have (3) Professional 36 (2) are Identical that require that you unscrew a white cap and blow the moisture out. The last one I purchased, pictured with the date of 1962 on the gasket has a button you push to release the moisture. The ones with the cap are better than the ones with the button, I feel you can get more moisture out. I would think you are correct especially if the use of the long thin mouth piece is used. From talking to friends that have broken theirs, it seams it is always human error (dropping) hitting the mouth piece. forgetting to take out the mouth piece before putting it in the case. The thin wall is prone to cracks by simply inserting the mouth piece in and out.
