Here is a nice bit from Greg Darnall that has a great feel and balance to it. Offers a slightly larger, non standard mouth size at 5 1/8″, all sweet iron with a thinner diameter mouth. Mullen mouth with a very small port, does move at shanks. Loomis style shanks that are swept back that measure 7.25″. Slightly longer purchase on this one. Nice bit, in very hardly used condition. Great training or using bit.
