Comment:
"No model. Model is missing or not identified. References were added because all vessels were built from the same plan 3-4 as per notes on the plan index card and the HMCo vessel name index cards. Note that offsets of this model have survived at M.I.T., which suggests that a model was made and may have survived, too. Notes by NGH in the offset booklet state that the model was made to an 1/12th scale, which, given that the launches built from it were 24ft long, indicates that the model was 24in long."
