Airsporter MK1 Questions.

[mrto]

Hi,
I aquired an Airsporter MK1 today the stock of which has no BSA logo embossed on the butt and the long stock bolt hole looks as though it was never threaded to accept a plug.The stock bolt itself instead of being a stud and seperate nut is all one piece.Is this in fact a MK2 stock or was there some variation of stocks and fixing bolts on the MK1's?
Secondly, the trigger sear adjuster is a rod that bears on the back of the trigger sear and has a locknut at its base.Is there an off the shelf tool that suits this nut has anyone found or does it require making a tool up?

Many thanks in advance.

Hi,
My Mk 1 is a GB serial and has the same features and was bought new by my Dad in 1958 ish, and has never been touched so is very original.
It does not have the BSA logo and no plug, and has the bolt and not the stud fitted. Sounds like it is original.
Hope this helps.Dean.

Yes,thank you that does help and good to know then it is all MK1 original.

Mark,
As above, these are standard features of early mk.1 Aisporters. There is no special tool for the adjuster locknut. I use a small ba spanner that I had lying around that just happens to fit. or , just use long nosed pliers.

Thanks Pete, I'm sure I'll find something to fit the nut.Would you be able to put the varying details of MK1 Airsporters in some sort of chronological order for me if poss' or direct me to where I may be able to swat up?

Cheers,
Mark.

Hi.I bet it is a one piece stock as well...Instead of the 3 piece unit?...If it is and you pop out the action and look at the stock in the area behind the trigger cut out, It should have stamped thereabouts "SILE".

The MK1's came both with a 3 piece stock and normal (on these) slotted stud / nut / bung grip fixing, but BSA contracted out stocks on both some firearms and the Airsporter at least in their air rifle range to SILE of Brescia, an Italian stock making company.

I don't know if this was because of the demand at the time,, ie. if BSA could not glue enough pieces of wood together fast enough, but the one piece stocks I have encountered over the years on MK1's all have the "MK2" style fixing, ie. large domed slotted screw and no bung in the smaller grip drilling, plus as you say, no heat impressed BSA logo.

The one piece ones I have encountered seem to be fitted more to GA or GB prefix guns, most G prefix seem to be three piece "normal" ones...I emphasise this is only what I have personally encountered, hopefully an Airsporter expert will be along to possibly clarify if possible when and why BSA used the Italian ones.

The one piece stocks normally last much better IMHO, less bits to go wrong!
