Did LeLand Brewsaugh do metal etchings?

Leland Brewsaugh is known for his lifelike carvings and sculptures of birds in Florida. He had painted and sculpted using different mediums and experimented with stained glass and ikebana flower arrangement. However, there are no reports of Mr. Brewsaugh creating metal etchings, at least not a regular basis. Hence, it would be difficult to provide valuation on works that have seen little circulation on the market.
