To my knowledge, I don't believe there were any side-stamped Tula magazines like that. Not to say the Tula magazine plant didn't make a few prototypes that remained at their factory, but I don't think any were ever fielded.
It's unfortunate they didn't though - a side-stamped Tula magazine would be neat.
