Congrats on the purchase. Would like to see more pictures of the overall rifle. The buttstock as I am sure you know is not factory and I believe that engraved trap buttplates could be commercially obtained to put on the new stock. I would like to see a pic of the forearm as I am not sure I understood your description.
If you get out and test fire it please let us know how it goes. The deer in your area should be scared. smile
