What's this logo?

[Bonefixer]

My late grandfather's watch. I can't identify the movement. On the bridge it says 'Swiss Made 15 jewels' and the logo is on the dial side. Case is gold, British made and says 'Stolkace' or something similar. Can't quite make it out.

I think it's a trust mark.

Hi. Reminiscent of the A.s.schild  mark. T/R in a shield and an A for Amida needs a bit more looking at.

More photos of the movement could help identify it but as @watchweasol said the TR is Schild

[Bonefixer]

Thank you. Having measured it, and looked at AS movements I think it might be an AS574. I've ordered one off ebay for £20. 
 

Reason I need one is I somehow lost the hour wheel. This was early on in my watch fiddling journey. I did have one 3D printed based on my own measurements and remarkably it works, but certainly wouldn't last very long. Time to put it back together properly cleaned, lubed, and give it back to my mum.

@Bonefixer, I'm working on an AS574 at the moment. Let me know if anything. 

[Bonefixer]

It's not a 574, it's probably a 341. The 34 should have been a clue to that

 I've put it back together and it's running. I've ordered an hour wheel from Cousins. The setting lever spring is broken, and a previous watchmaker rigged up a solution so it works as it should.

Anyone know what the TR connection with Schild.

I posted before, I think it's a trust mark. AS may of made the  ebouches but an independent watch maker assembled it. The trust mark was to indicate his/her competence.
