WILL IT FIT???

Just the Cylinder, Blued, measures 1.984-1.985, good shape.

Anyone know, would this fit a 1957 Flat Top????? THANKS

The cylinder in the link looks like a NM (big frame) cylinder to me...so no, it won't work in an OM FT regardless of OAL.
In other words, it's too fat and the chambers are too far apart...and that's that.

No Sir, the front stub (gas seal) is way too long for an old model,cannot tell by the picture as to the diameter,spacing of the cylinders.........................gotta put 'em "side by side" or better yet MEASURE the actual cylinder.........


here is a drawing my friend Roland Kirsch did for Bill Ross book.......

Well THANKS. Too bad.
