Can anyone help???

[Mdbh]

Can anyone tell me what year these are? I had a look at the guide on the museum and cant tell?

I forgot to say obviously there kneesavers?

I would say they are gen 4. Being straight across the top without the curved ends on the stem tube. Would be good for 90-94ish.

I can't see what 1's they r because they don't have the ruff bit on the cross bar?

Arr if there is no knurling (it's hard to see that on my phone) then these are the Haro remakes of the kneesavers. Only made a few years back. 
You require some the same shape but with the knurling. I think ed209 had some. Pm him.
