The bullet/emitter back and halo are all smaller on mine and the dimensions of the handle a tad narrower. I didn't change them to match Russ's version but changed them to match the dimensions of the original prop based upon revised measurements taken from screencaps and stills of the original. I had other information from a sonic guru and TLP and we put it all together in that sonic. The design and original dimensions are open to much interpretation and argument, I just put together all the info I had to make the prop more accurate to my way of thinking. The only thing I'm sure of are the emitter sizes and halo being smaller than the ones currently on offer. Russ's bullet is alot smaller than others and I'm sure the original prop was smaller than that...
In Ark in Space the sonic looks much shorter than has currently been offered (very much Russ's sonic size), and the halo is never larger in diameter than the cone at the top of the handle, but smaller in diameter than the handle base unit.
Crappy picture, but you get an idea of the small size of the bullet emitter in Pyramids if you compare it to the black neck bullet. This also shows the small size of the halo compared to the main body diameter.
