Battery Base

I purchased the battery base pictured below a few years ago. Noticed recently a number of bases with three holes in them rather than the one as in mine, different years/suppliers? Appreciate if anyone knows why.

Can anyone shed any light.......appreciate the minute a battery is on top of it such detail is lost but when did that ever stop us!

i repoped this part years go and noticed the same....the sample parts i had came off the same tool..this i could see from the same imperfections on the parts that came from the vac forming tool...my two cents = early ones had only one hole

This one was in my '65...

so my theory is probably wrong...
my new theory:they figured out that one hole is enough...and safed 10 secounds of labor

Gents, thanks for the input.

Can anyone else add to the above with a few more examples where they are known to be original?

Hi Tim,

The two 1968 911 that I have access to have just one hole. Both have their original battery tray.

Thanks,

Brad

Thanks Brad, interesting.

Cheers
