Help i.d. Vintage 60s(?) 10' yater longboard

Yea the tail block definatly looks suspicious to me the way the glass ends right before it. The fin also is not original, reshaped from the original maybe but i kinda doubt it. Ill try post some pics of the fin as soon as i get out of the fricken dmv. Thats also my next question for the experts. What fin to use. Seems like spoon fins are pretty readily available

If Deadshaper doesn’t know, the Poolman probably would.

What ever happened to the Old Pool Man??

heres the fin

8" tall about 6" base

I seriously doubt that is the original fin.

“I seriously doubt that is the original fin”…

Again, not an expert but I’m of the same opinion on the fin.  Regarding the Poolman… he is the guy who turned me on to the penciled in ‘Y’ directly below the logo information. 

Here is a photo of him cranking a cutback on his 12 foot Andreini glider…

Deadshaper!? Poolman!? Where you at? Haha

Thanx everybody for the help, the fin is lame as shit. Especially how it got attached or maybe attacked is more accurate.
