I'm considering a DIY drum roaster build. I was at a national dairy goat show yesterday(no espresso booth

) and saw one of these. 4.5" opening 6"diameter 9.75" to the lip. quite heavy stainless. Talked with the sales guy and can get it without the handle too.
I'm wondering how the size compares to a Quest drum.
Anyone know the M3 drum approximate dimensions?
The thickness of a quest drum if known too.
