Winchester sold a Miroku-made (same as Brownings before them) Lo Wall in .22 LR. You see them on sites like GunsAmerica. Most I've seen are "Hi Grade" models, with some engraving ... otherwise "traditional" style, with 1/2-round/1/2-octagon barrel, straight stock, crescent butt plate. Prices for these tend to be around $1000. The newer versions of these are in .17 HMR, with full octagon barrel & modern-style stock (like the recent Browning LoWalls). I think Winchester makes a different caliber each year; maybe they'll do another run in .22, but without the fancy "do-dads" (the current .17s seem to cost around $800)
