Chris Pickford has drawn our attention to the fact that any bellframe indicated as having a truss type starting 8.3.C... should show cast iron and nothing else as its material type.
As a result, we have already added that material type to such frame records as were showing previously without any material being specified, and those which were shown simply as being of metal have been amended to being of cast iron.
It is our plan to do the same for those 7 instances currently identified as being of steel (on the grounds that there is much confusion on the part of ringers between steel on the one hand and cast iron on the other). That leaves a large group (82 instances) of such frames showing as that generic truss type but identified as Steel/CastIron (StlCI), a smaller one (24 instances) of Oak/CI, and 3 Comp (composite).
If you have been the contributor of any of the above frame descriptions and feel that your classification of material was absolutely correct, we invite you to get in touch with us.
