Harry Williams' rare Bally designs (1971) likely resulted from Sam Stern's brief executive role at the company.
Harry Williams designed two traditional pinball games for Bally: Firecracker (Feb 1971, 2,800 units) and Skyrocket (May 1971, 545 units)
high confidence · IPDB records and production data cited directly
Sam Stern purchased 49% of Williams Manufacturing from Harry Williams in 1947 and the two became friends
high confidence · Video Game Historian source and historical records cited
Sam Stern felt embarrassed about aspects of buying Harry out in 1959 and allowed Harry to continue developing designs as an external contractor for Williams
high confidence · Steve Kordek (Williams designer) interview recollection
Sam Stern worked for Bally as executive vice president from 1969-1970, coinciding with project dates for Firecracker (July 27, 1970) and Skyrocket (August 3, 1970)
high confidence · Multiple period magazine sources and IPDB project dates
Two additional Harry Williams designs (Samoa and Bali-Hi) were produced by Bally in 1971 but credited to Ted Zale at IPDB, with project dates of September 1970
high confidence · Duncan Brown's playfield design documentation and comparison analysis
Firecracker's original design was called 'Scramble' in Harry Williams' files before Bally renamed it
high confidence · Duncan Brown's collection analysis and design comparison
Steve Kordek had no interest in building Harry Williams' designs at Williams and preferred to develop his own, though he preserved many of Harry's designs
high confidence · Kordek interview recollection
Sam Stern returned to Williams (under Seeburg ownership) in 1970 and stayed until 1976, after which he founded Stern Electronics
high confidence · Period magazine sources and historical records
“Sam Stern felt embarrassed about aspects of buying Harry out in 1959 (Kordek indicated it was regarding the amount of money). Sam allowed Harry to continue to develop pinball designs as an external contractor and submit them for possible production by Williams.”
Article author, citing Steve Kordek — Establishes the precedent of Sam Stern supporting Harry Williams' external design work, which provides context for the Bally collaboration
“Kordek did not see the point in building Harry's designs when he could build his own.”
Article author, describing Steve Kordek's perspective — Explains why Harry's designs were not pursued at Williams despite Sam's openness to them
“Brown's playfield records indicate Harry worked on all these designs in June 1970, and that they were Bally templates (so Harry did intend these games to be made by Bally, not Williams).”
Article author, reporting Duncan Brown's findings — Confirms that Harry Williams specifically designed these machines for Bally rather than submitting them as Williams options
“Given what the pinball community knows about the relationship between Harry Williams and Sam Stern, I think there is enough convergence on the project dates and Sam's employment with Bally to suggest it to be the primary factor for this interesting fluke of pinball design history.”
Article author — Synthesizes the circumstantial evidence supporting the Sam Stern hypothesis
community_signal: Pinball design attribution accuracy and credit assignment challenges in early 1970s; Sea Ray and Bali-Hi credited to Ted Zale despite apparent Harry Williams authorship
medium · Duncan Brown's design comparison showing high similarity between credited Ted Zale games and documented Harry Williams designs with matching project dates
design_philosophy: Sam Stern maintained an open-door policy for external contractor designs from Harry Williams, suggesting manufacturer leadership philosophy prioritized designer relationships over internal design teams
high · Steve Kordek's recollection that Sam Stern allowed Harry to submit designs despite Kordek's preference to develop his own; replicated pattern across Williams and Stern Electronics
market_signal: Sam Stern's personal relationships with Harry Williams directly influenced which manufacturers produced Harry's designs across multiple decades and companies
high · Convergence of Sam Stern's employment timeline with Bally (1969-1970) and the project dates of four Harry Williams designs (all dated in June-September 1970)
neutral(0.5)— The article presents a historical analysis with scholarly tone. The author acknowledges uncertainty ('I have no confirmed answer') while building circumstantial evidence. The narrative is appreciative of the historical connections uncovered but maintains academic skepticism about causal claims.
