I just received a Hohner Super Chromonica Deluxe, Key of C. The images of the harmonica on the seller’s site had chrome or stainless steel cover plates. Mine are gold tone. I’ve looked around and don’t see any discussion.
jaya, the standard 270 chromonica also came in a Gold version, so you probably have these cover plates. I don’t think its in production any more, although parts are available (or at least shown on the Hohner C-shop site).
Ssssh, don’t say that too loudly or everyone will want them
Seriously, the series Super Chromonica Deluxe is fitted with stainless steel covers, as shown in the online catalogue. The regular Super Chromonica is however available in a version with gold plated covers, possibly you were sent that by mistake. Can you post a photo?
