In 1920, the Birmingham Small Arms Company supplied 10,000 Pattern 1907 bayonets to the government of Siam to accompany an order for rifles. The original maker of these bayonets was unknown, but historical research indicates that the Wilkinson Sword Co. Ltd. was a primary maker. The weights of some surviving Pattern 1907 bayonets, including twelve bayonets from the 10,000 described above, produced by the six makers in the UK before and during the Great War (1914–1918) period were available. A statistical analysis of the data was performed to compare with the historical research. The results strongly supported that the Wilkinson Sword Co. Ltd. was a primary maker. They were also sufficient to exclude from this batch of twelve bayonets the Royal Small Arms Factory (Enfield) and Vickers Ltd. as manufacturers. The statistical evidence for the presence of bayonets made by J.A. Chapman Ltd., R. Mole & Sons and Sanderson Bros. was weaker than that for the Wilkinson Sword Co. Ltd., but was nevertheless supportive of that hypothesis. Overall, the analysis was consistent with the supply to Siam of commingled bayonets from British government stores. It was noted that the bayonets for the Siam contract fell into a relatively narrow weight range, but the reason for this could not be determined.

统计分析作为历史研究的辅助工具：确定伯明翰轻武器公司于 1920 年向暹罗政府提供的英国 1907 年刺刀的可能制造商

1920 年，伯明翰轻武器公司向暹罗政府提供了 10,000 把 Pattern 1907 刺刀，以配合订购步枪。这些刺刀的原始制造商未知，但历史研究表明威尔金森剑有限公司是主要制造商。一些幸存的 Pattern 1907 刺刀的重量，包括上述 10,000 把刺刀中的 12 把，由英国的六家制造商在一战（1914-1918 年）之前和期间生产。对数据进行统计分析以与历史研究进行比较。结果强烈支持威尔金森剑有限公司是主要制造商。他们也足以将皇家小型武器厂（恩菲尔德）和维克斯有限公司作为制造商排除在这批十二把刺刀之外。JA Chapman Ltd.、R. Mole & Sons 和 Sanderson Bros. 制造的刺刀存在的统计证据比 Wilkinson Sword Co. Ltd. 的要弱，但仍然支持该假设。总体而言，该分析与英国政府商店向暹罗供应的混合刺刀一致。有人指出，暹罗合同的刺刀属于相对较窄的重量范围，但无法确定原因。
