Dating fathers Super Chromonica 270

I’m trying to date my fathers Super Chromonica 270. I don’t remember him playing it very often and I haven’t played it since he passed. It appears to be in excellent condition.

I appreciate any information any cares to share.

Thanks

It’s hard to date harmonicas as they generally don’t have serial numbers. According to the list I have from the Harmonica Museum in Trossingen, the Super Chromonica was first manufactured in 1928, but this one is unlikely to be that old. The original packaging would be a better guide.
