Kramer Pacer challenger strat 1979 Blue burst

I bought this Kramer Pacer new around 1980 but I don’t remember the exact year.  I was told it was the first non-prototype production of the model. It was ordered at the NAMM show from Kramer.  I got Kramer to issue a letter on the production number and they confirmed it was one of the first ten made. The letter is included with the guitar
the guitar came with a German made Rockinger tremelo system. It was a heavy  brass bridge.  It had a locking nut as well. The original Rockinger has been replaced and the bridge on it now is a Fender bridge. It sounds much better with less mass in the bridge. 
 The original pickups are included with the guitar.  They are not in the guitar. The original pickups are Seymour Duncan’s.  The pickups in the guitar are Almafitano boutique pickups.  They are classics. 

The original case is included but the handle is missing and it has been chewed on by my guard dog.  In other words the case is a bit rough on the outside.  
This is a cool guitar great sound great player.
