Producing Points, Pittsburgh Area" (Old Code #446.3, New Code #10-14-46.01). There Is No Change In Commodity Specificatons At This Time (July, 1948).

There Seems To Be No Change Except For The Fact That The Quotation Is Now In"Dollars Per 100 Pounds." Bulletin Nos. 877 And 920 Do Not Make This Clear. However, The Monthly Mimeographed Release Shows A New Series, #446.2. This Is A "Substitution, Rolled, 11 Gauge, 36" To 48" Wide, Per 100 Pounds, F.O.B. Basing Point." Bls Bulletin 947 Carries This Series Back To January, 1947. In The New Index, The Series Code Is 10-14-46. Source: 1947 Data Are From Bls Bulletin No.947 And Monthly Mimeographed Releases. 1948-1958 Data Are From Bls, Prices And Price Relatives For Individual Commoditities In The Revised Index: 1947-1950, Bls Bulletin No. 1143, And Monthly Issues Of Wholesale Prices And Price Indexes, 1952 And Following.
