Yamaha Helix questions???

[BLUE DEVIL 700]

I've recently bougth a couple of old Yamaha Helix's for litte or nothing but have no idea what angles they are..i think there Straight cut but not possitive the only numbers i can Find are
3 8BV 10 on one and 3 8BV 70 on the other...I have no idea what kind of Sled they came from,Hoping there is some kind of way to idenify them.
Any Help would be great.

I don't have the SRX anymore but I figured this was the best place to post this!!

Figured out that the 8BV10 is a 41* Still wondering about the 8BV70

Straight 47* if I am not mistaken

yes, you guys are correct. the 8bv70 is a straight 47 and the 8bv10 is a straight 41.
