Possibly vintage bongos?

I got these from a guy that I was learning from back in 85 & they were pretty used back then. Pretty sure they are a bit old. I put them away for like 6 years, I did not play for a long time & the skins were both ripped open after while. They were the original skins. I started to play again now & I put some new skins on them & man they have such a good tone. What model you guys think that they are? Thanks..
