Replacement Laser Cannons for the 1/32 scale Monogram/Revell and Moebius Colonial Viper Mk1 model kits.
The two parts are identical except for a small mounting hole that is used to pin the part to the model at the correct angle.
This is a digital version of the cannons I mastered the "old fashioned way" a few years ago. Details for those resin items are available at http://www.fireballmodels.info/fmr-011.htm
