mpfirnhaber Posted June 29, 2015 Posted June 29, 2015 I would love to see a timeline of the different slotted brick variations out there. I think I know the relative chronology, but I'm fuzzy on the dates. Were GEAS/Prima being made at the same time as no-logo bricks in Denmark? When did bricks start coming out of Norway? Were there any other locations making slotted bricks? Maybe someone could help me fill in the blanks :) GEAS (Sweden) Prima (Sweden) No Logo (Denmark) Short G Short G Fat Long G Hatched (Norway) Long G Edged Number Dogbone Quote
WoutR Posted June 30, 2015 Posted June 30, 2015 As far as I know, no overview exists until we make one :) This is a good overview of the DANISH parts: http://www.historia.com.pt/legos/Textos/bricks/2X4brick_vs02.htm The Swedisch, Norwegian and Icelandic versions are not included. As far as I know.... - The Swedish GEAS/PRIMA bricks were made 1950-1955. First sold under the GEAS name, change to PRIMA around 1953. These names do not correspond exactly to the brick versions. The GEAS bricks were of the common "no logo" version. These are found in both Bakelite and CA. I think these have also been found in a PRIMA box. Later, the factury used the "targetbrick" mold. I think those have only been found in PRIMA boxes. - The Norwegian bricks started 1953. Initially using molds that were used in Danmark before. We have found the "no logo" version and all types of blockletter logos. The Long G Hatched and the slotted bricks with hollow studs seem to be Norwegian only. - The Icelandic bricks started in 1955 As far as I know they received used molds, I am not yet sure which type. (No logo again?) Quote
WoutR Posted June 30, 2015 Posted June 30, 2015 We will have to look at the details in original sets with known origin and date to find the missing information... Quote
LEGO Historian Posted June 30, 2015 Posted June 30, 2015 (edited) From what I was told several years ago by TLG Archive folks... The no logo bricks were produced from 1949-55. The block letter bricks were produce from 1950-56 The dogbone bricks were produced from 1954-56. The no logo molds may have ended up (eventually) in Sweden (Geas), Norway (A/S Norske LEGIO) and Iceland (SIBS Kubbar). The block letter bricks were produced in 1x2, 2x2, 2x3, 2x4, 2x8, 2x10, 10x20. (the 1x2 and 2x3 were introduced in 1952, the 2x8, 2x10, 10x20 were introduced in 1953). The dogbone bricks were produced in 1x2, 2x2, 2x3, 2x4, 4x4 corner, 2x12, 2x14 and 10x20. (The 4x4 corner,2x12 and 2x14 bricks were introduced in 1955). As to specific mold types within the variations of the different fonts.... we may never know start and end dates. Records were not kept, and it's like saying when was the last old gray part sold by TLG? Add into the mix things such as when did the filled in slots to the formerly slotted bricks start, and when did the last dogbone part end is further confusion. My first LEGO set ever, a 1960 700/1 basic set had all tube bottom bricks, and a 10x20 gray baseplate without LEGO on the studs, and a dogbone font underneath. LEGO Mayhem. In doing all my LEGO research, I no longer spend a lot of time dealing with things we'll never get an accurate answer for. Ditto for the Geas ABB and PRIMA bricks of Sweden.... when did they use Bakelite and when did they use Polystyrene.... we'll never know. The Geas company has no records of it. In fact TLG and Geas have no records of ever collaborating on sets/molds. Edited June 30, 2015 by LEGO Historian Quote
mpfirnhaber Posted June 30, 2015 Author Posted June 30, 2015 Thanks Gary. Yes, there are a lot of unknowns, and there always will be. But I think more is known now than was know 5 years ago about the history of slotted bricks. Who knows what else we'll know 5 years from now! I think there are a few transitional molds, however, that will always be a mystery. Double logo slotted, hollow stud blockletter slotted, bricks with filled slots, bricks with no slots and blockletter logo underneath... Lots of oddballs! It's amazing that entire molds were created for these and yet nobody knows much about them... Quote

LEGO Historian Posted July 1, 2015 Posted July 1, 2015 Unfortunately "known origin" has issues as well.... I know of many old time collectors that have "restored" their sets. Finding sealed sets from the 1960s is almost impossible to find... sealed sets from the 1950s are almost non-existent. Here's a sealed 1960-65 700/0 set.... no one will want to "unseal" it to check the parts!! Quote
