Very off subject I am trying to source some shell bearings for a 250 enfield. Hitchcocks is out of stock . The shells are marked with a G,glacier?, in a square with the number s9387s this is not an Enfield number. Years ago we used to use austin A40 devon  main bearing shells I presume a more modern replacement have been found . I am hoping someone has a bearing catalogue that they could check for me . . The big end journal is 1.750, -.030 , the width of the shells are 19.50mm.They look suspiciously like 1275 mini shells but I have no patterns to check.
