Wolverines are all pee-wee or smaller, Bifurcates all have an opaque base of two different colors, not sure what to call it except Killer Nice marble Art.
I don't think either of yours is Alley IMO. If you look @ my OP the Alley insulator has a corkscrew pattern and the other doesn't the same as yours made by another manufacturer. Ron & Bill pointed out the differences after I made an incorrect post on AAM.
Look what I found on Feebay, the OP's Brother & yes it's a wedding cake

Yes they are the genuine article, wish I had a date for you Brother !! Older I know that much, the newer ones (& mimics, i.e. fakes) have no pleated seam, maybe try and PM @Al Oregon ??
Can I bid first ?? Can I ?? ... ... They better cut back on the dope habit a little bit man, they're beginning to hallucinate "Badly" they're not even all Ravenswood ..
The bags have a pleated seam in the middle of the back to help ya date them, they look 100 authentic to me. Maybe @Al Oregon will stop by and give you an exact date, wish I knew more ??
No Akro, no Peltier, no Veiligglas, you're whittling it down there, fewer and fewer options will ultimately lead to the proper I.D. or @ least leave one of 2 choices. Let the fun begin
