These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. and have been kept in storage for some years, we have therefore classified them as ‘new other’. As can be seen in the photographs they have been marked with a tick, this was done prior to them coming to us as a result of in house testing.
