Was at the local gun shop today and found and old Daisy Model 25. It has a wood stock and on the top of the receiver it has DAISY No 25; DAISY MFG.CO.; PLYMOUTH, MICH.U.S.A.; PATENTS PENDING. Coated with rust, seems to work(cocks and fires when trigger pulled-need to get some BB's). How do you tell if it is a long or shot pull. Stock is not a pistol grip.
