Hi all, if anyone could help date any of this (I've search-barred and googled etc.. to no avail):

This is all in one unit:

1x Fane loudspeaker - cast iron chassis, 15ohms, 22watt (serial no. can be provided)
1x Dubiliser Metalised Type 418, 150V (?!)
1x Celestion High Frequency Unit, 15ohm (Hf 1300 Mk 2)

I'm yet to find out if it works but it all looks untouched and it's been in a loft for years.

Any info on any of this would be great!
