BF3 Post purge timer

Happy Sunday gang

It's been a few years since I've worked on a Riello BF3

I do remember having to replace the original post purge timers on occasion. I ran into one last night that has the what I assume is the original K7R C583006 control. Can you tell me if in fact it is the original? and is it replaced with the C7001084? I feel like it is stirring a memory. Like I say It's been a long while.
