Kentucky 2-piece stock kit

I picked up a kit rifle at a farm auction for a few bucks and want to see if I can make it shoot. I assume it was a CVA or Traditions. Only marks were on barrel saying Lugar and Spain. It was "assembled" but nor stained. The end thimble fell off just from handling as did one end of the ramrod. I got these back on and noticed the joint at the brass stock divider was a little loosey goosey. When I took it apart the only thing holding the stock assembly to the barrel was the end cap screw and the tang screw. At the stock joint were two pins (~2") that went in holes in each piece of the stock parallel to the barrel. The barrel was cut for an under lug, but none was there. Anybody tell me what I'm missing? I can make an under lug and pin, but just wonder if there was a part left out.

Is there an inlet in the stock for a lug, and a hole for a pin? Might as well put one in there.

You're certainly missing a pin for a thimble, and for the brass RR tip.

Make sure to do a slight counter-sink on the RR tip on both sides so that you can peen the brass in to it from the cross pin. I little bit of super glue in the hole won't hurt anything either.

Those 2-piece Spanish gun kits aren't renowned for being of the highest quality, so I wouldn't go too nuts in devotion of time to it.

Spanish and In twoo parts it's wrhited on "Jukar Spain" or "Dikar Spain" ?
This si a Tradition Kentucky rifle made when the name of Tradition was Jukar, Dikar or Ardesa (the same fabrication but name changing with the time), with a join in the wood this is certainly a kit...
If the barrel and adjustments are good you can shoot with this, normally the barrel is not marvelous but fine good...
If all is right it eats .440 bullets, 0.25mm patches and 55grains (maximum) of BP. I had one before that was eating 45 grains...

Not spending much time with, just an easy tinker. No inlet in the stock for a pin, but I'll put one in. Just thought I must be missing something. All the thimble are attached to wood only with very short screws. Looks like a short-lived arrangement. My plan is just to finish it up, make sure its a safe shooter and give it to someone with an interest but has never shot black powder. Somebody did that to me with a recurve bow 50 years ago and I've loved bowhunting and shooting ever since.

Yes, this is a kit and that is why it looks so poorly, but you can easily work on that rifle and get a relatively good rifle (see if the the barrel is not rusty): the barrel is good, the normal twist is 1:66 for patched round balls of .440...

The convert from percussion to flintlock or inverse is really simple and the locks Traditions (unchanged since Jukar) are good enough and for very low cost...

You can make happy a young (or older) guy with this: I know peoples shooting with this with pleasure with those rifles: at 55yards that works well and can stay in 2x2" on a board or bench and with open sights...
