Lodge catalogs do not list a 6 hole version of this pan until the 30-40's catalog. The dimensions of that pan are 5 ˝" X 7 3/4" with a weight of ~3lbs. No picture of the smaller pan is available.
The 1950's and ‘68 catalog indicate dimensions of this pan are 5 ˝" X 8 3/4" with an approximate weight again of 3lbs. No photo again.
At first glance, I thought this pan looks more like BSR’s Century muffin pan, because of the open triangle in each ‘handle.’
