Same ol ones here. All purchased new in early 1980. I was on a long-barreled kick.

Model 29-2


Model 14-4


Model 17-4


There used to be an 8 3/8-inch Model 27 on hand to go with them, but when it was discovered to have a "slow barrel" it later went away in favor of the 6-inch Model 27 that would yield higher velocities over the chronongraph with any load tried.
