So, I'm in a little bit of a rut, so I have an older model of the SP "Daylight" which seems to have been sold during the 1984 Louisiana worlds fair, the left cylinder assembly has broken and I plan to replace it. When I bought the engine off E-bay it was all there except the manual, I don't feel comfortable taking it apart without knowing what I'm taking apart, I've looked up and down to find the manual for this model and hav'nt found it yet, could anyone point me in the right direction? The item number is 41-0550-D9 if that helps any...

So I've just received one of those old collectors exclusive Bachmann Norfolk and Western #600 class "J", so its obviously quiet old I've read the maintenance manual. My question being that the smoke unit seems to pop every now and again before returning to "normal" order, during the time it pops its sprays some smoke fluid about, I'm unsure if this is normal behavior for the smoke unit considering the part in the manual is numbered "2911" and no other smoke unit has acted in this was. (sorry for any unnecessary information) Any help would be very much appreciated.

-Cheers, Gage
