Anyone heard of a 70 point board?

I found a cribbage board at the Goodwill that goes up to 70 points - has 70 holes??

It says pressman sure-lane on the front but it is set up like a traditional wooden board for 2 players- no colored "lanes" like the other pressman boards.

I can't find any information online.
Maybe it is a counterfit "knockoff"? Lol

It was only a dollar so I bought it as a joke, but then I read that some boards were used to score other games in "the olden days".

Anyone know why they made this? Thanks
