I'm looking for the Surefire tapeswitch pictured below. Now that the model number is SRxx meaning that it's the SR switch and the last two are the length with the most popular model being the SR07. I'm not interested in the other version that only has momentary on/off whereas this model has the click on/off option as well. I've seen them sell for $50 shipped used so that's what I'm looking to spend. Must be in perfect working order and not on it's last limb so to speak. PM or email with what you have. Thanks for reading.
