Thick glass longnecks and heavy duty cardboard cases

Ah - the good old days...
Started brewing in '87 by getting 20 cases of reuseable bar bottles in heavy cardboard cases from the ole college bar.

I'm looking to get more bottles and cases and it seems that the days of reuseable, thick glass long neck bottles in sturdy cardboard is long gone...

I've bought a case of the "new" bottles, but the carrier and the bottles are just now as "heavy duty" as the old bar bottles.

Does anyone have any ideas
[1] if any companies still uses the old bottles or
[2] if they are available elsewhere.

Thanks!
