Today I stripped down the HW35 Lochschaft to see whats inside. I found an original steel spring guide with two bits broken off and floating around loose in the rear of the cylinder and a completely shagged spring of the Ox square section variety. Fortunately I had another spring (albeit too long) and a guide from another rifle with I carried out slight modifications to. I ended up cutting a coil off the spring, heating it up and re'shaping to finish. Its now cleaned up, regreased and shooting lovely on open sights. I reckon I will keep it on opens as there is a bit too much movement in the barrel to scope it up. The zero at 25 yards was inches rather than mm but on opens its grouping around 30mm so not too disappointed at all. A fun afternoon for once
