123-Ignition distributors

[linwood rose <linwoodrose@mac.com>]

I was planning on going with a Mallory unilite distributor for my  
BT7, but recently came across the 123-Ignition distributor. I wonder  
if anyone has any experience with this distributor. From the website  
it is not clear to me if it works with the mechanical tachometer as  
fitted on the BT7. Thoughts?
