Straube

Three-tier horizontal valves. The valves are not the normal type found in horizontal valve actions, which were usually the wire i pin variety. The Straube used a swinging valve which pivoted from between two "ears" that were an extension of the metal plate.

The valve was a wooden disc faced with leather on both sides; one facing had a center hole and a pocket in the wood, of a larger diameter, behind. The only thing that supported this valve was a lever between the valve plate pivot and the pouch lifter disc, with a right angle dowel extension which "plugged in" the center hole of the valve button. This pivoting lever could be quickly removed, since it was not glued to the valve, leaving the valve button loose in the valve well behind the valve plate, which was screwed onto the valve chest with some type of white sealing compound.

Since "Player-Care" is an internet business, I prefer that we correspond via E-Mail (click here to fill out the 'Request Form'). However, if I'm not in the middle of some other activity, you can reach me at 732-840-8787. But please understand that during the hours from 8AM-5PM EST (Mon-Sat), I'm generally quite busy. So, I probably won't answer the phone. If you get the answering machine, please leave a detailed message stating the reason for your call. Also, repeat your name and phone number clearly and distinctly. By necessity, I prioritize everything in my life. And, if you call and just leave your name and number, and ask me to call you back, it might be a day or two before I return your call. Why? Because I don't know why you want me to call and I might not be prepared to assist you in an effective and efficient manner. If you leave me an E-Mail address (which I prefer), spell it out phonetically. The more you do to help me, the more I can help you in return. Don't rush. You have four minutes to record your message.
