Glencroft was trained by David Chapman at Stillington, just outside Easingwold, was owned by Martin Wane (Light Blue, Light Green Sleeves, Black Cap) he won 9 Handicaps from 5 furlongs to a mile in 1988, that same season Chapman also trained Chaplin's Club for Peter Savill (Maroon, Light Blue Sleeves and Cap, Maroon Diamond) who won 9 handicaps over 5f and 6 furlongs, Chaplin's Club had also won 9 handicaps in the 1985 season and won his last race at Redcar in 1992.
I think Kevin Darley rode Chaplins Club to all 18 of those handicap success and that Stuart Webster was aboard Glencroft for most of his wins.
