Composite photo of an H.G. CD 151 that has no H.G. embossing. It's a crude piece with a lot of stuff going on inside, and a pretty rough surface. It looks like it's from a reworked mold where the H.G. was left out by mistake. Clearly, there is no "blot out" visable...just crude surface markings. Other pictures of the embossing available if you want them...contact me!! Don Briel will be adding a new listing in the next Guide: It is tentatively CD 151 PATENT - OTHER [010]
