Thanks.
This bit of research has piqued my interest, too.
For instance, there are two
1955 CM tool catalogs on OWWM/VM websites. A
Power Tools Catalog and a
Mechanics' Tools Catalog.
From the
Power Tools Catalog.
1/4-HP 'Underwriters' Laboratory approved.' RT CI pre-Block, 44# $32.50.
1/3-HP 'Underwriters' Laboratory approved (Industrial Standards).', 'Heavy-duty production-type. Ideal for factories, machine shops, garages, mills, any place where a top quality, tough grinder is needed.', rear exhaust ports, RT CI pre-Block, 59#, $48.95.
1/2-HP 'Underwriters' Laboratory approved (Industrial Standards).' 'Built for industrial use...ideal for heavy work in machine shops and factories.' RT CI pre-Block, HD base. 85#, $66.95.
From the
Mechanics' Tools Catalog.
1/4-HP, UL Seal, CI RT pre-Block, $35.95.
1/3-HP, UL Seal, 'Larger, heavier, with more power and greater adjustment' than 1/3-HP, 59# vs. 44#, UL (Industrial Standards), rear exhaust ports, 7x3/4" grinding wheels, CI RT pre-Block. $49.95.
1/2-HP not included in catalog. ?!?
I thought maybe the
Mechanics' Tools Catalog came out prior to the
1955 Power Tools Catalog, but the prices are higher than they are in the
Power Tools Catalog and the 1/2-HP pre-Block was available in the 1954 catalog
.
Further surfing of some available CM tool catalogs on the OWWM/VM website did not reveal any technical changes from the
1954 introduction of the round top, pre-Block grinders.
The following shows the pricing of the pre-Block grinders.

@ Note: "The Recession of 1958, also known as the Eisenhower Recession, was a sharp worldwide economic downturn in 1958." "The effect on prices and costs was an apparent paradox, as prices continued to rise while production and employment were declining."

OK, then why are the 1959 pre-Block prices less than the 1957 prices?
Remember - 'You can tune a piano, but you cannot tune a fish!'
