Hi chaps.

Last week I purchased this Haenel 28. I have admired these air pistols for years and am glad to have found one.

Serial number is 8130. Does anyone know how this dates the pistol?

The power is very low, even for such an old pistol, and so I am thinking of putting in a new seal. Problem is... I have no idea what I'm looking at in terms of wear. Does anyone have a view on how worn the existing piston seal is?

I welcome any views on the condition of the internal parts on this pistol, and what I could do to improve the power.

Very best regards to all

Will
