This is an extension speaker only. No amplifier etc. It's pretty rough, and comes complete with borer holes. But it has the potential to clean up very well.

As can be seen here, there is absolutely no indication of manufacturer.

Fortunately the front panel, which will be shellacked, has no borer holes, although the sides and top, which will be painted as per original, have. So they will be easily disguised.

All done. Finished. Finito

It certainly looks really good now! The wood grain shows up very nicely.
