[0.81] Aran/Neo Tokyo

Well, actually... The weapons aren't that easy to make. You need 4000 silver coins total. 3000 to make the weapon and 1000 to upgrade the stone. I've gone up to the fourth area of Future Toukyou and I only have around 975 silver coins. :X

Wondering if we could get more info on how the weapons (1H sword specifically) are made in jms. From what I've been able to find on this thread and the one in general...

No stims, no crystals, but this is a makered item.
-How do we learn the recipe?
-I know it's 105 base, can this still go +/- 5 or does it always come out at 105?

From the picture posted I see 2 items I don't know what, a Dragon Carabella? and 3000 of those silver coins. I'm thinking the first 2 are NT drops/items with the "stone" needing to be upgraded with 1000 silver coins. How do we get the two items? And are they tradeable? Are the silver coins tradeable?

Thanks in advance, I tried to look through the thread and a few other places before asking but didn't find anything to specifically answer my question, but could have easily missed it due the massive in the thread.
