Hi Reece,
An AA5 with six tubes. I could never figure out what to call it.
You're right about the inlay. It's a photo tape on top of the wood. The finish isn't too bad. I might try a restorer product like you mentioned.
I haven't opened it up yet but by peeking in through the back it appears that the speaker has been replaced once. I think there is room for a higher quality speaker like you suggest.
I'm not going for complete originality. I will completely recap it and use safety caps where appropriate. The speaker can't be seen anyhow.
But, in the interest of some basic originality, were these small wooden sets usually shiny or have a satin finish? I saw a post on arf saying that they were shiny. I kind of prefer satin.
