 The firm made a variety of lithographed metal wind-up toys. Both Jewish, they moved to Britain following Hitler’s rise to power in 1933.

Johnny Lightning is a brand of model cars originally produced by Topper Toys, similar to the hugely successful Mattel Hot Wheels die cast racing cars.
 Their claim to fame at that time was that they were extremely fast compared to other brands of die-cast cars.
 Their most important technology was to mold in a small hook under the front axle so that they could be propelled by a lever-driven catapult, far faster than could be obtained by either gravity, or battery powered "supercharger" devices.
 Topper closed in 1971 and production of Johnny Lightning cars ceased for 23 years.
 In 2003 Thomas Lowe secured the trademark rights to the Johnny Lightning name for his Playing Mantis company.
 Playing Mantis produced toy cars under the Johnny Lightning brand name from 1994 to June 2004.
 At that time Playing Mantis (including the Johnny Lightning brand) was bought by RC2 Corp. which in turn was bought by the Japanese toy company TOMY in 2011.
 TOMY discontinued the Johnny Lightning line of diecast cars in 2013.
 The brand continued to maintain a following by a loyal group of collectors.
 In early 2016 Round 2 LLC, a toy company owned by Thomas Lowe (who also owned Playing Mantis), revived and reintroduced Johnny Lightning vehicles to the toy market for a second time.
Corgi Toys (trademark) is the name of a range of die-cast toy vehicles produced by Mettoy Playcraft Ltd. in the United Kingdom.
 The Mettoy (Metal Toy) company was founded in 1933 by German émigré Philip Ullmann in Northampton, England, where he was later joined by South African-born German Arthur Katz, who had previously worked for Ulmann at his toy company Tipp and Co of Nuremberg.
 They decided to market a range of toy vehicles as competition to Meccano's Dinky Toys model vehicles, which had dominated the British market for many years.
 Corgi Toys were introduced in the UK in July 1956 and were manufactured in Swansea, Wales, for twenty seven years before the company went into liquidation.
 A management buy-out re-formed the company as Corgi Toys Limited in March 1984.
 In 1989, the management sold the Corgi brand to Mattel and the factory was retained under the name of Microlink Industries Ltd.
 In 1995, Corgi regained its independence as a new company, Corgi Classics Limited, and moved to new premises in Leicester.
