Hi have uploaded some more pictures of the superlight reciever.also uploaded pictures of another a5 I have.dont know if it's the right barrel for it.

Serial number 153693 was made in 1929. What’s more, it’s engraved, which was an expensive option. Your gun has considerable collector value. The barrel should have a matching serial number stamped at the base of the barrel ring. And, on this one, the date code will be among the proof marks.

I don’t think any Superlights were made in Japan. But I’ll dig out my book tomorrow and see what it says.

Hi thanks for all the help.thats interesting about the engraved a5.
