Yes it does look very much like Hundredweight!
Definitely not a variety sown by me this year. Very true with the mistaken cross hand pollinating, one I did this year was meant to be Sibley x Potimarron, but it turns out the Sibley mother plant was in fact already a hybrid! Right shape but wrong colour! My mistake, maybe next year I'll have another go. Although if it tastes good I may try a few of the mixed up cross next year.
