I'm sorting through my surplus parts and have these two cylinders which I believe are for 24-29 J Model H/Ds. Stud holes are at 3 1/4 inch centres (pre-24 is 3 I/8?). Don't think they were originally a pair as the rear cylinder has noticeably more nickel remaining than the front one. Also, though I don't have a micrometer to check the bores, the rear seems to have a bit more "meat" left than the front - perhaps the original bore. The front doesn't appear to have any broken fins; rear has two.
As I don't know much about post-23 models, and whether there were any subtle variations in cylinder castings between 24 and 29, I'm simply looking for confirmation that I have got the id right. (I've apparently got the camera to focus on the background rather than the cylinders but they should be clear enough for identification.)
I'll shortly post a photo in the "Other Harley" section of the forum of what I believe is a cylinder for a single.
I'd also be grateful if anyone can offer a view on my earlier post about inlet manifolds
