Note that this is a SOULBOUND item, it is Binds on Pickup.

Learned from Техника: свиток продаж, which can be bought from Рабул once you have reputation level 5 (Esteemed) with Консорциум ремесленников – филиал на Драконьих островах, which is the maximum reputation level with them.

Summons a vendor that sells some supplies, which is notable since it can (presumably) be used indoors and buy your trash items (where you can't summon vendor mounts, etc).
Has a Quality 1 (Свиток продаж), Quality 2 (Свиток продаж) and a Quality 3 variant (Свиток продаж).

No idea whether Свиток продаж is consumed or reusable since it is BoP with a cooldown.

No idea what items are offered by this vendor per quality, or who it actually summons. I will try to get my hands on one and test it, will update this post when I get the results.

Can confirm that anyone can use this merchant. I summoned one outside an ah and asked my friend who was not grouped with me if they could use it and they were able to.
He also has the option for repairs so, it's essentially a Scribes version of Jeeves.

Summons Странствующий торговец. Offers repairs, and sells some general crafting mats.
Also sells Кружкой по макушке for healers who run out of water (not as good as Кисло-сладкая похлебка из моллюсков, but will do in a pinch). Goods will vary based on scroll quality.
The Свиток продаж is BOP and currently cannot be work ordered, so the only way to get it is to be the scribe that crafts it.
I was able to purchase this at only 3/5 Consortium rep with my scribe alt. I believe that as long as one of your characters is 5/5 with them, it unlocks it for your alts.
Your raid/ party can use it.
There is a 6 hour CD on using it, so it will not replace Автоматический молот.
