I asked Grok and good to know when they take over even they will be citing Bert 😀 see below…

There is no known “official” statement from Winchester (or its later corporate owners) explaining the reuse. Extensive searches of Winchester histories, factory records summaries, collector publications, and the company’s own timeline/FAQ turn up nothing—no memos, catalogs, or executive comments addressing it. 

The best (and only substantive) explanation comes from knowledgeable Winchester collectors and historians, particularly those associated with the Winchester Arms Collectors Association (WACA). In a dedicated discussion on this forum, WACA Historian Bert H. addressed the Model 59 pair directly and offered the same logic that applies to the Model 55s:

“I suspect that somebody at Winchester forgot about the Model 59 .22 rim fire rifle. It was developed in 1929, and only marketed for one year (1930). It was discontinued after just 9,293 were manufactured. The Model 59 Semi-auto shotgun arrived on the scene 20-years later in 1959, which leads me to believe that whomever it was that assigned the model designation to it, was unaware of the Model 59 rifle from 20-years earlier. Of course, this is just my guess.” 

The same reasoning fits the Model 55s perfectly: the lever-action version was discontinued in the early 1930s, and the .22 version appeared ~25–30 years later. Both early models were relatively low-volume or short-lived (especially the Depression-era .22s), so by the late 1950s/early 1960s—when Winchester was rapidly introducing new budget .22s and shotguns under new corporate ownership (Olin)—the prior uses of those numbers had faded from institutional memory.

Why not just pick a new number? Model numbers at Winchester were primarily internal marketing/designation tools rather than strictly controlled, trademarked, or sequentially “reserved” identifiers. There was no production overlap, no parts interchangeability issues at the time, and no consumer confusion in the marketplace because the guns were sold decades apart in completely different categories (centerfire rifle vs. rimfire plinker; rimfire rifle vs. shotgun). Winchester was churning out new models rapidly in the post-WWII era, and a simple two-digit numbering system made reuse administratively convenient. The company almost certainly never imagined that collectors decades later would be cross-referencing old catalogs and serial lists.

In short, it was an unintentional oversight driven by time gaps, low production of the originals, and a lack of any formal “model number registry.” It has created minor confusion for modern collectors and appraisers (you always have to specify “lever 55” or “.22 55,” for example), but it wasn’t a problem for Winchester at the time. No evidence suggests it was done deliberately for any strategic or marketing reason.

I suppose that sort of explains the Model 1887 shotgun and Model 87 Winder Musket. Sort of.
