The gun is a MK2.
Its a project that is in the loft and its almost time to come out. However I compared the .25 barrel to a barrel I'm sure came off the Merc and the slots are different.
Not sure I'd like to dremmel the slot really but may try it.

Very strange, John, what is the serial number on the .25" barrel you have ?

After a quick search it appears that Knibbs are knocking out .25" BSA barrels at a good price. ---
