We have received feedback that more guidance might be given on categorisation of bellframes. Our users are reminded that one section of our Help facility explicitly deals with Editing Bellframe Details, and does so in some detail yet without repeating the extensive contents of Chris Pickford’s scheme which are fully documented in his book. If the truss and layout information cannot be determined then we would MUCH rather have the other details (maker, material, date) than show nothing at all: the definitive information can always be added subsequently.
