motor ID/crystal questions

[Shonen]

Hey guys, I have a couple of questions and hopefully someone can help me out...

First off, I found this brushed motor. I have not seen anything like it before, and perhaps someone can help identify it, direct me to a datasheet or at the very least enlighten me on how it works so I can possibly use it for something (probably non-RC related, as it's ~20lbs).











I didn't get a photo of the armature, but from what I can work out it's a normal brushed arm but with many many poles (20?). The case of the motor seems to be used as a ground as well. The iron slabs on the case seem to be electromagnets, as they did not attract my screwdrivers even when I touched them directly.

Secondly, this question has to do with receiver crystals. I have a couple GWS micro receivers (R4PII) but the crystals have died. Amain has such an awesome sale on crystals right now that I bought several replacement regular-size crystals for $0.40 each to experiment with, but obviously they are not plug and play into the GWS receivers.



As far as I can work out there is not enough UM-1 size crystal popularity for there to be commercially made adapters. One of the only things I have not soldered before is a crystal resonator. Do RC crystals have enough heat tolerance, or am I better off soldering a socket to the board?

ps. maybe I'm just being dumb but I can't seem to find pcb type crystal sockets for sale anywhere. "crystal sockets", "crystal adapters", "crystal pcb" etc...none of my searches turn up anything. I suppose I could cannibalize some Xmod boards (or DIP IC sockets) but for future reference where do they sell these (and what should my search string be instead)?

Thanks guys!
