    Used on some late 1940s early 1950s Ultra "Twin 50" models, but later models used separate HT and LT packs, taking about the same space,

    LT part is 5 x F or 5 x D cells and HT part is possibly 4 series stacks of 14 layer / "biscuit" cells.

    Dimensions are from a retail price list but a prototype replica fits an Ultra "Twin 50" model (all are same dimension of case & chassis)
