Direct answer: It’s not clear what you’re asking with “wm 202.” If you’re referring to a specific item, here are a few likely possibilities and how they’re commonly denoted:

• WM-202 locomotive: Western Maryland Railway No. 202, a preserved 4-6-2 steam locomotive built in 1912. If you’re looking for its history, current status, or location, it’s historically tied to Hagerstown, Maryland, and has been listed on the National Register of Historic Places. Some discussions mention a 202 restoration or relocation considerations as of recent years. If you need the most up-to-date status, specify whether you want its historical background, technical specs, or current custodial status.

• WM-202 microphone: A dynamic handheld microphone model from mid-20th century Japanese manufacturers (Panasonic/Matsushita/National). If you need its electrical specs, era, or compatibility, I can summarize typical moving-coil dynamics and impedance ranges for that class.

• WM-202 personal electronics: Several product lines (Walkman-era players and radio devices) use WM-202-like designations in different markets. If you meant a particular device (Sony Walkman WM-R202, WM-F202, etc.), tell me which brand and region, and I’ll pull exact specs and release notes.

• WM 202 other contexts: In biotech or corporate tickers, “WM-202” could refer to a research compound or a stock/fund ticker in some datasets. If this is finance or pharmacology, please specify the domain so the answer can be targeted.

If you can share a bit more context (are you asking about a locomotive, a microphone, a consumer electronics device, or something else with the designation WM-202?), I’ll provide a precise, detailed answer with the most relevant facts.
