I don´t understand you, Oddball....First you state the drum must be out of round, and when (partly) convinced it may not be, then you say it soon will be!
Are you trying to get the drum for yourself?
This drum is more then 30 years old, and if it is round, it very probably will stay round. The hoops and heads will have helped the shell staying round.
Now, I can´t see the drum, and neither can you, I guess? But ask the seller for a couple of pics, showing the drum seen from above and below with hoops but no heads attached - this will clearly show any ovality.
ASBA made hundreds of drums like this, I have seen and toyed with three complete kits, and they are no joke. This is high quality gear.
