Anyone recognize this case coloring?

Dean, that 16 ga vh of mine that youve handled was restocked and case colored by DelGrego about 6 or 7 yrs ago. Maybe longer. Their case colors on the bottom side of the frame did not wear well and the underside is practically clear now. Im wondering if this was a cynanide job and do cynanide colors not hold their colors as well as other case coloring processes. Im tempted to send the frame to Brad Bachelder and have Brad recolor it. His colors have stood up well on my other parkers that hes done for me

Allen, I've been told the cyanide case colors are more durable than traditional bone/charcoal and they tend to last longer. Cyanide colos typically are more intense for sure. The floor plate of my VH looks like a tequila sunrise.
