Magazine cover of 1970's Muay Thai fighter ... what magazine is this, who is he, and when was this published?

[FOARP]

Hi. We're having a discussion over on Wikipedia about the article of a certain Rabieb Sangnual who got silver at the 8th Asian games in the light middleweight class, and competed at the 1972 Olympic games. We don't have anything for this guy other than an entry in a list of people who competed at the Olympics and got medals in other events, which isn't enough for the article to be kept - for it to be kept we ideally need a biographical article, obituary or similar.

A search has turned up this magazine cover (or it looks like a cover anyway, could be an inside spread, or even just a fan-made picture - it's certainly had a lot of water-marks added to it) on Facebook of a Muay Thai fighter who went by the name Khongdetnoi Lukbangplasoi. It looks like the same magazine as some of the pictures here. I think if we could find this magazine and show that this Muay Thai fighter is the same person as Rabieb Sangnaul (not just fans in a FB thread saying this, but evidence from a reliable source) then probably the article could be kept.

Do you know who this fighter is? Was he Sangnaul? Do you know what magazine this is? When was it published? Sorry about all the questions, but this is an unfamiliar area for a lot of us, for sure most of us don't speak Thai (I don't anyway), and it would be great to have the benefit of your expertise.

The facebook post says he fought for Rajadamnern Champion 147 pound title. One comment said he was Lumpinee champion, and my favorite comment says he was the man who read out the weights during morning weigh ins, when the commenter first started fighting at Lumpinee.

This is Muay magazine, from the 70s, which the collection I've been able to get my hands on are only covers, no inside sheets. So I don't have access to an article that might cement this image, but I will ask a few sources to see what I can get.
