Well that Bamboo was sort of a jest, but I do recall reading the MauMau did make homemade shotguns using Bamboo wrapped with wet rawhide which then shrank tight for re-inforcement. As they were stealing the Brits shells to shoot them with, they were of course using 12ga shells & no doubt sought out a much better fit.
