Ted.
What do you mean when you say the AM no.is in a different sequence to the others ?
I know what BT35-8's AM no. is , and also BT30/36 BT30-27.

If I understand correctly , it appears that Moser's car was stuffed and they recieved on Ron T's advice a BT36 frame to rebuild their BT30-17 , however to ''assist '' in border crossing the car was retained on it's original carnet, and as the Swiss Customs people were more diligent than others , that there may have been some numbers supplied to help.

We have two scenarios available here, and the simple answer lies in finding out if the whole damaged BT30-17 returned to the works in the U.K. or if a new BT36 chassis and presumably other lesser components were dispatched to Moser in Switzerland.

If the former , there is no way the old dead chassis is going to return to Switzerland , as it would complicate customs.
AM numbers were put on by Arch Motors not Brabhams , so did Mosers mechanics add another number elsewhere to assist customs entry , because we know the AM no. on the BT30 is going to be AM70-?, and the AM no. on the 36 is going to be AM71-?, and that is not going to be helpful at the border.

As we appear to have one BT30 dead , and a BT36 , with it's own number i.e , BT36-11 , and recorded as such by F1R , which is used to rebuild the dead BT30 , really one assumes BT30 ceased to exist at that point in time, and BT36-11 took over.

Therefore at what point in time did BT30 resurface and under what circumstances.
Only two scenarios are poss. , out the back door from Brabhams in 1971 , if the car was rebuilt by them, and I for one would love to see a verifyable trail on that.
Or the BT36 new chassis was sent to Switzerland and the dead BT30 lay doggo for an indeterminate length of time and then resurfaces, surely at that point only a rusty chassis.
I would love to see a verifyable trail on that as well , but more importantly what are the AM numbers on both these cars, as I don't understand your reference to a different sequence.

In regard to the body panels , that is why at the start of this thread I expanded on that , as it was always going to complicate matters.

To answer your question , re. the frame , in OZ apart from one memorable stuff-up , the old dead frame is no more than another consumed component , along with wheels brake pads , uprights , and everything else that has either worn out or been crash damaged.

Beat says that after Imola the new frame was in the car , but always with the old number , not according to F1R.
Rouen 27-6-1971 , Moser has BT30-17 , and is on the grid.
Imola 25-7-1971 , Moser has BT36-11, but does not start due to crash.
Entered for Mantorp Park , but dns , car not ready, HOWEVER , car entered as BT30 .
At Tulln , dns , car not ready , but entered as BT36.

At Albi , on the grid , but did not qualify , but F1R records as BT36-11, also at Hochenheim, and at Vallelunga, 10-10-1971 and 17-10-1971.

F1R is saying at Imola Moser already had BT36-11 , is this a serious typo , or did Moser have two cars the old BT30-17 , and the BT36-11 and damaged BT30-17 , and Ron replaced that with a BT36 chassis into the BT30-17 , by the sound of it , Moser was struggling to pay for the new chassis and bits , so unlikely he had two, therefore F1R may be wrong.

Something is all wrong here.
