George,

Nice example of a pre-1945 Erma 'Model 30' conversion kit.

Here's one in use:

I believe this small box 22 conversion was manufactured in mid 1937. I have fired it several times and I do have to attest they are nice to own, however they do not function with a dam. Granted the E/77 10 round magazine has a weak spring so I purchased a post war 22 conversion magazine with stronger spring and results were the same.

With only 30,000 made, I am very fortunate to own one. I was surprised many years ago to see that ever the spacer & nuts were proofed as well as all the other parts!

Lugerdoc here in the forum gave me the advice to remove the ejector before installing the set. Made mine function quite flawlessly, perhaps you have it installed?
btw. spring is supposed to be a bit weak on these .22 mags.

Steiner:

Many thanks for your response. Is your 22 conversion unit war time or post war?

I have always heard good things regarding the post war units! I am aware that the ejector should be removed hence the slot in the wood box.

My guess your unit is post war as I have never heard anything good regarding the function regarding these war time 22 conversions.

Spring tension on post war magazines is about twice what my war time unit is and they are .22LR not .22 mag.
