Hard to say exactly Jan, as I didn't measure it at the time. Seems like it was perhaps about half again as long as my middle finger and about that big around, or just a tad smaller, so call it 4-5 inches (120-150mm) and 1/2 inch or so diameter (50-60+mm), but I'm just guessing in hindsight.
The stalk it is on is about 3/32" (~1.5-2.5mm) diameter with pod spacing of about 1/2" ( 12-14mm) if that helps any.
Yes it was relatively big and fat compared to most of its kind, though certainly not the biggest nor fattest that I have seen.
