The Bedford OB with it's Duple Vista body very much represents the heyday of British Coach Travel, this small 29 seat coach proved the ideal vehicle for many operators in the early post World War II years. The classic coach was a popular choice from the late 40's until the early 50's, many active examples still exist in the hands of preservationist's today.

The OOC versions comes in two versions either with or without quarter light roof windows, prior to the OM4xx series the two versions were issued in separate series, 425 with quarterlights and 426 without, all models since 2001 have been issued in the OM426 series regardless of type.
