It MAY- depends on which Browning and which Miroku. Browning moved production of some firearms to Japan, where they were produced by Miroku- so there IS some relation between them. Really need to check with a gunsmith, or staff at Numrich, gunpartscorp- with their staff.
Your browning lever action 22 was made in 1976.
The Browning SA-22 was invented by gun design genius John Browning around the 1920s and was one of the first autoloading 22s ever offered. Most of John Browning's designs were made by other companies until the Browning Arms Company was established in 1927. The gun was made by the Remington Arms Company as model 241, from 1935 to 1949. Browning Arms Company recovered the rights to the SA-22 and began producing it as a prestige, top of the line gun in Belgium. Currently it is being made in Japan. The SA-22 has been in continuous production for almost 75 years with only slight cosmetic changes. The Browning SA-22 is produced in several models for various 22 cartridges, differing only in receiver engraving and barrel shape. All are funtionally equivalent. The currently produced Grade 1 gun retails for $571. Grades 2 and 3 have been dropped as not offering enough of a step up for the increased price. A grade IV model with gold washed engraving is now sold for $1171. Firearms collectors regard the Browning SA-22 as one of the best of all rimfire autoloading rifles. Guns produced in Belgium are the most valued by collectors, used Model 1 guns in mint condition selling for over $1000. The machining is of the highest grade and the stocks are made from selected furniture grade walnut. Indeed, one of the problems with owning such a gun is that many consider it too beautiful to use. Too bad since it is one of the best plinking and small game weapons made. If you intend to use the gun in the field, opt for a Remington 241 or one of the later Japanese models. You will not suffer angst if you scratch the receiver or get a gouge in the stock.
