There's no need for special lubricants,just a little automotive moly grease for the moving components and some vegetable oil for the piston seal.
Don't forget to check the mainspring free length,a standard spring should be around 240mm.

thanks for the info i shall check out the spring length when i reassemble
the spring in mine is measuring in at 22.6 cm
breech seal looks in reasonable condition to me but i will photograph it tomorrow and post it on here for a second opinion
well what a difference a clean makes
took the whole lot to pieces and cleared out all the grease someone had put in there ( more grease than gun)
anyway before i went ahead and ordered any parts for it i figured id put it back together lubed up behind the piston seal ect and got it all back together and had a test shot at the same scaffold board in the garden about 20 ft away and here are the results
before pellets were not even going into the wood to there own depth skirt was sticking out about 2mm
now its gone into the scaffold board about 3 or 4 pellets deep
so i would say that is a marked improvment while i know it has not been chrono'd (dont have one) will hopefully pop it to a friends who has one and see what it is officially putting out
all in all not bad
Sounds as if you've had a result,an operating Mk1 for £25 .
I remember Terry Robb stating in his buyer's guide that they would often produce better power than Airsporters of the time.
They only used steel for the first year of production ASM then went to plastic in 1960 I think
This is mine, (.177) It looks a bit tatty as it's nickel plated and is worn in places but shoots sweetly with plenty of power!!

It's an early one (N268) with the steel end cap and usual missing rearsight ...

yes i hear the rear sight is usually missing on these mine is there tho
Well if it wasnt for all that grease it would be a right dog. Just wish others used it. A friend had one that was found in a shed and ive seen better conditioned old railings.
Grease is a lot easier to get off than paint or varnish

Have you had a chance to test it through a chronograph yet?.
