I've been looking into this more, all WP countries evaluted the T-62 at some point. and apparantly only Bulgaria accepted them. According to David Isby, Bulgaria as of the late 70s early 80s, had about 100 T-62s. Some sources I've looked at says in the early 90s, Bulgaria decommissioned between 300-400 T-62s. This either means Isby's estimate is to low or Bulgaria continued to recieve more T-62s in the 80s.

Bottom line is Bulgaria does indeed seem to have had T-62s, so my orginal post that this was an OBB error is incorrect, I based it on the assumption that the T-62 was not exported to WP nations: only T-55 and T-72 models. Bulgaria receives the T-62A (with the 12.7mm AAmg) in 1971 according to the Bulgarian OBB right now.

I know a small bulgarian force took part in the events in 1968. If the article you found is not a typo, it could mean that Bulgarians had the T-62 as early as 1968. But the Bulgarian military was generally less advanced then other WP countries, so it would be a big suprise for them to have such an advanced tank, for that time. The blogger must have meant a T-55, (its easy to confuse the two).
