[78-L] English Columbia Matrices

[Roger Wade]

I need some help in dating two English Columbia test pressings.  The  
matrix numbers are:

RAX 2658

RAX 2659

I want to think they are from 1927 but I'm hoping someone on the list  
will know for certain.

These are two single-sided 12-inch 78s with the Columbia and 2 notes  
embossed on the plain side.

The recordings are the Queen Mab Scherzo, Parts 1 and 2, by Sir  
Hamilton Harty and the Halle Orchestra.

Thanks in advance for your assistance.

Best regards,

Roger Wade
