French Longboat oars

Does anyone have any drawings of oars for French longboats? I am building the Unicorn kit, it roughly corelates to the ANCRE "Armed Longboat - 1834" monograph. The kit does not include oars and I would like to scratchbuild some.

I suspect the ratios of the parts would be similar to those of the English oars. Maybe contact the Musee de la Marine as they are usually very helpful. https://www.musee-marine.fr/nos-musees/paris.html Phone and email are at the bottom of the page. If you are OK with the English ratios, those by Steel should be close. The biggest problem with oars is that the majority seen on models are much too short. The oars are typically 3 to 4 times longer than the breadth of the boat. Note that where the loom is called out as square, but sometimes were oval or round.
