James S. Burke Jr. Musician, model maker James S. Burke Jr., a jazz musician and a maker of ship, train and architectural models who had a reputation as a perfectionist in both vocations, died Tuesday after a heart attack at his home in Fells Point. Mr. Burke, 50, had been ill with diabetes and kidney failure. He became interested in building model trains in the 1960s, but the business he had operated since 1991 -- Museum Quality Models -- specialized in making ship models and displays for architects from their building plans. One of Mr. Burke's customers was a tugboat company, for which he built 25 scale models of a boat to be used as corporate gifts. Born in Baltimore, Mr. Burke was a graduate of Douglass High School. He studied music there and at Morgan State University. His military service, from 1966 to 1968, was as a drummer in an Army band. He played drums in professional jazz groups in Baltimore and Philadelphia into the 1980s. He often played in the 1970s with the Vernon Wolst Trio. Major Boyd, a saxophonist who had known Mr. Burke since high school days, recalled him as "a strong melodic drummer who encouraged and supported me when I was getting started." "He was a good friend, a loyal friend," Mr. Boyd said. Before starting his model-building company, Mr. Burke worked in an interior design business. His wife of nearly 26 years, the former Leah Davis, described him as "a perfectionist who paid astute attention to detail in both music and model making." "He was extremely dedicated to what he was doing," she said. "He wouldn't let himself be sidetracked." Graveside services will be held at 1 p.m. tomorrow at Garrison Forest Veterans Cemetery, 11501 Garrison Forest Road in Owings Mills. In addition to his wife, his survivors include two sons, Hammond Burke and James Grant, both of Baltimore; a daughter, Joan Grant of Baltimore; and five sisters, Barbara Lightfoot of Palmyra, N.Y., Marilyn Queen of Columbia, Jo-Ann Holly of Seabrook, N.J., and Janet Oskay and Nancy Spencer, both of Baltimore. @ Robert L.
