I am building one for my grandson. It is a 3/4 sized Isaac Haines in a A weight 36" Colerain barrel, in .40 cal. Fully dressed the rifle weighs 5# and it has a 12" LOP. Small Siler lick, single Davis trigger, small Bivins T/Guard, Buttplate, & Entrypipe but cut down to 3/4 size, then made the sideplate like a Bivins sideplate but at 3/4 size. It is a cute lil rifle. If you need some photos I can take some & email them to you.
