Here is the classified ad clipped from that issue, putting the Spiers 
business up for sale(!):

I found it via newspapers.com, which has the Manchester Guardian as well 
as thousands of other newspapers. I have used it extensively in 
documenting the Black & Decker Workmate. For just one example, see some 
of the clippings I collected about Ron Hickman's original Workmate:

decker

They have various rates, including specials every so often. My first 
subscription in 1921 was 1 month for $20. In 2022 I got 6 months for 
$55, and then this past November I got 6 months for $50, both as 
discount offers.

A great deal of the info that I posted here a few weeks ago about the 
publication date of the Practical Woodworker came from newspapers.com.
