Mike,
3 16ga Lefevers in less than a year must be a record!
Those are some high stock dimensions especially the F as it is a early gun.
I have 12 or so Lefevers 1 16ga 1 20ga and the rest 12 ga. I have a 12 ga G 32" steel late gun with 1 7/8" drop at heel wood to 12 1/2" and 1/2"spacer with 1" pad(butt ugly!). Another 1`2ga G straight grip with 2 1/4" drop 14" long with pad included.
I don't leave to go hunting until tomorrow and me and "Gus" my GSP can't wait. Other than doves and yard birds he has not seen a wild bird yet. I hope to get him out west next year. I have had him to a couple of preserves this fall and he is pointing and retreiving well. The preserve cover is thin so when he sees the birds running around on the ground he wants to rush in sometimes. I think a real covey rise will open his eyes.
You realy should have a D M Lefever 16 ga. with Krupp barrels and stocked to 1 1/2 x 2 1/4 x 15 in grade 6 or higher! I'll give you until next week to find one. OK maybe next month but NO LONGER!!
Please take me Quail hunting in Texas. I will buy all the Lone Stars after the hunt and bring you a 12 ga 8E D M Lefever to try out if you can carry it after being so spoiled carrying those light 16 ga guns.

Fritz
