TechManual gives us lists of prices for components and the formula for coming up with the total C-Bill cost of a BattleMech made from those components.
Do the component costs and final vehicle costs represent the manufacturer's cost to make the unit in question (in terms of labor, raw materials, overhead, etc.) or the retail price. Black market modifiers are applied to the price given, when using those RPG rules, so it appears to be the retail price. In that case, is there any sort of official rule of thumb for estimating the manufacturer's cost?
(I know 'whatever works for your game' applies, but I wanted to check if there was anything official that I'd missed.)
