Lamblin radiators

Do we have any experts in Lamblin radiators out there? Specifically, can anyone provide excat dimensions for the ‘lobster pot’ type? Most sources say that they came in several sizes depending on the cooling capacity required (logical), but from what I can see from photographs (Nieport-Delage, Curtiss, Gloster etc.) only one size seems to have been used.

My reason for asking is that the ‘lobster pot’ fitted at the last moment to the Blackburn Pellet may have been a larger size, based on what limited photographs are available, and I want to determine whether that is likely or not.

Thanks
