but I am not sure what you really needed to know.
That new edition's ducktail was indeed a unique one.
Fences appear on all the Comp Daytonas.
The 64 was realeased twice, first as restored and ages later in race spec.
That car was a bad choice by Kyosho, while it was the only Comp with rounded rear arches, so probably this new mold made them delay the LM cars so long.
And then they made too many at once....

Good luck with the move... this sounds like a heck of work, knowing the size of your collection!
