"I'll be in touch," Seoraj promises, looking pleased; he doesn't mind the usual work, shoeing horses and repairing wheel axles, making tools for farmers, but this is a little more engaging and he's confident he'll be able to produce something more than workable for Ianto. Maybe he'll look into these guns himself, too, but that's a different flavour of curiosity. "You let me know if there's anything else you need." In general, he means, not right now. Presumably if there were anything else now, he'd have said as much.
