The highly collectible No.4 MkII* bayonets by Baird were known for their fine finish, the spike blade was steel pinned rather than welded to the socked. 

Baird Engineering of Belfast only made a total of 75.000 No.4 MKII* spike bayonets . The same number (or somewhat more) as No.4 MK1 cruciform blade bayonets were made by Singer.
