The quick answer is no I am not selling them,
However if you were to ask me can you get one the answer is yes.
I have a machine shop and I made a standing offer to UK members to help if I could with machined parts for their build, members need to cover the cost of the raw materials and postage.
JonnyB asked me to help him develop 2 versions of this phaser pistol for my part I am developing the mechanisms for the barrel and machining the parts. The pics of the one I uploaded are for the cage version and is only a prototype which as mentioned in the text has a functioning front ring to align the laser diodes, the centre ring floats but has a magnet in it to operate a reed switch within the barrel and a functioning rear ring as a power setting. the second version was used in the episode “Where no man has gone before” this one operates a little different as it extends both front and back. and has twice as many parts with an internal mechanism to allow it to operate. The intention is for the barrels to be fully functional with the ability to take electronics both for sound and working laser diodes which Jonnyb is doing. The current plan is to build 3 of each type one prototype and 2 finished for our own collections.
If you are looking for a non functioning plain static barrel that is a simple task. which I can do reasonably quickly. If you are wanting a functioning barrel it would be best to wait until we finish building the 6. as we are still tweaking the design.
Either way let me know what your after and I will do my best to help.
