Stahl & Associates ??

[68l30]

I am looking for some info on a Stahl & Assoc. mech tach assy.It is a 9/10 grand tach made by Jones Motrola.These later evolved into a Moroso only tach sometime in I believe in the early 70's.I have noticed a variety in names from 68 to 70.I have seen a Stahl & Assoc. name on some and Stahl & Moroso on others.Both were circa 1968.I have a catalog listing for 69/70 from Motion with the Moroso name whited out by Motion.Anyone know the association between the involved parties.Which came first,I believe it was Stahl...Does anyone know which mounting bracket was used with a Stahl tach? The earliest one I have seen had the "old" Moroso Performance logo.I have never seen a Stahl labled bracket...Kind of some oddball questions but I find very little info on these in my area.Is/was this more of an east coast speed part?Thanks....
