Default What Corvette is this from?

I'll try to attach a photo. I don't do this much...
Here's a picture (maybe) of an expansion tank I bought around 40 years ago...just in case I ever needed to replace the tank in my 1962 Corvette. I still have the '62 & have decided I don't need this tank any longer. It reads "HARRISON 3151016 FILL 1/2 WHEN COLD 70H". I'm guessing it is for a 1970 Corvette, but never having had one (or any other C3, I don't know.
Can someone tell me what this fits?
Thanks,
Mark
Northern Kentucky

Mark,
We need to see where the outlets are and what direction they face. It could be 61-62, or 63-67,or 68 -71.

According to GM Parts, your tank number corresponds with '61-'62 "second design". (Early C3s used #3016340 from '68 to '72.)

Wow!
I looked at the original tank on my '62 and it is the identical part number EXCEPT it shows '61K' where the one on my picture (above) shows '70H'.
Mystery solved thanks to your help. I feel a little better about my decades-ago purchase having been the right one for my car.
A lot of this 'numbers matching' stuff is beyond my pay grade.
Again, thank you.

70 H means it is from a 1970 Corvette. I read that GM would only make three tank parts runs a year, so there are only three letter (month) codes. My tank had a C. Lou.

The '68 to '72's all used the same #3016340 tank, not this #3151016; I agree that it appears to have been made in '70 though.
