OK buddy here is my take on it.

Now let me start by saying that whilst I have been for the most part an enthusiastic army collector I usually only collect the early stuff with unique fittings. This has generic fittings so not really my preference or something I would normally get excited about, however I do have one of each generic type as a representative example in my collection.

This is a very fine looking dagger & one I would be very happy to put in my collection. The condition is outstanding and SMF is not a common maker if you collect by maker marks. If i did collect by maker mark I would much rather have this SMF with generic fittings than one produced with their own early hilt fittings because the quality was pretty poor (unless you got a brass based example). SMF `in house` x guard is by common consent just about the most hideous thing ever produced and I would certainly prefer this one.

If it`s yours congratulations & if you are thinking about it then go for it! NICE dagger!
