Bosch kill switch - difference between old en new production?

[911_2.2T]

Is there any difference between the new production Bosch kill switch and the old stock vintage ones in quality or markings?
Or is there perhaps a data stamp on these?
I came a accross a batch of old stock of these switches from an old army depot. They are at least from somewhere i the eighties, but perhaps even earlier on.

I'm trying to determine if there is any value in buying their stock, since the new production ones are fairly cheap and shipping is quite costly to the US, at this point it does not make a whole lot of sense to me........(unless someone would buy a box full of these from me and distribute them across the board members in the US?)

Pictures of one of the old stock attached.

I have two very old Bosch switches. The handle is not removable. Not sure if this was more of a race version or what. I will get some pictures tonight...

Thanks,

I'll dig mine out over the weekend and snap a couple macro shots to compare.
