TBH if it's accurate then I would leave it for now - not sure if the washer is leather but if it is then a couple of drops of neatsfoot oil down the transfer port then leave to stand overnight will be all she needs.

With any new gun (second hand or brand new), a strip, clean, examination and proper lube is always beneficial.

Check seals (barrel and piston) for wear, look at spring and see if still straight, check for any sharp edges in cocking slot, wear on piston, internal bore of compression chamber etc.

Put back together with original parts and see how it settles.

If you still feel it requires a bit of fettling, basic Tinbum tuning kit, new spring and new piston/barrel seals.

Piston seal should be plastic or some such. 

Watch out for where the lever entered the cylinder, mine was rough and made breaking of the barrel harsh. Also these things are made to be over the 12ftlb mark, mine was over by a long way and took a bit of work as back then I didn't know what I was doing to get it back. If its accurate now, leave it as is. If your getting 2'' groups at 25yards it's time for a service. I sold mine as it was as rough as a Badger, but brought home the bacon so to speak.
