I'm sorry N-M but I'm even more confused.
Terminology first: B7 is the old British 7-Pin Base. B7G is the modernish small 7-Pin Base. B9A is the modernish 9-Pin Base and Octal, of which there were two flavours, are 40s onwards 8-Pin Bases. There are Pictures on the national Valve Museum Website - http://www.r-type.org/search.php
Which are we talking about?
Are the Bases still in the Chassis? If so, what are they? A Picture would help.
If the Bases are missing then what size are the holes? If that's the case you're going to have some real fun deciding which wire goes where.
I have seen the odd Set where the Manufacturer fitted an 'Adapter Plate' in order to use a different Valve, but it's unusual.
