Freewheel Identify Help

[broady]

Can anyone tell me what freewheel cassette this will take:

Looks like an old Uniglide freehub...is the bike 6 speed ?
If it is its perhaps worth youtube'ing to assess what can be done..

Size wise, it looks to take a 8/9 speed

Probably not uniglide then, IIRC they had threads on the splines to accept the locking sprocket.
