Intertype and Linotype measure liners are stamped with both the point size and the ems measure, and are placed in the left hand side of the mould as seen from the front of the machine. Liners for the right hand end are stamped only with the point size.
These liners look to me as though they are ordinary right hand mould liners that have been drilled to accept wedges. This means they could be used upside down at the left hand end of the mould, giving the maximum measure, usually 30ems, unless you have a 42em machine.
You're machine is English-built so make sure you use only English moulds, mould liners, matrices and space bands on it. Even though it's built to use the British-American point system, American and British machines are different.
On Intertypes, British moulds are stamped .843 (the height of a blank slug), and the matrices stamped with a letter E between the point size and the fount reference number. British Linotype matrices have a diamond between the point size and fount reference.
English matrices are struck to a depth of 0.075 inches (75thou), which is then added to the blank slug height to give .918, i.e. type height.
American-made matrices have a struck depth of 0.043 inches. This gives type height of .918 inches when added to the American blank slug height of 0.875.
Don't mix British and American machines and/or parts, keep them separate. Use only English matrices on English machines, and American mats on American machines.
If your machine measure scale goes up to 28 then it's the French Didot system, which I know nothing about!!!
Good Luck.
