What can you tell me about this upper?

I know what you are wanting to do, and it can be done.....I did it. Since these lugers were all hand fitted when manufactured, you will need to check the parts of your upper receiver to your frame. Some need a fair amount of work to fit correctly, others, not so much. You may well need to play with springs(main) depending on what is currently in you Alphabet luger.

I found a 1939 receiver that had been rebarreled with a 5in bbl, and I fitted a complete Erfurt toggle train to it. I now can switch back and forth between the calibers. I am a reloader, so I have a load that requires no spring changes.

Good luck.
