This is an accurate reproduction of the 91-A base in Umber Gray color (we are out of the Black color). The photos are of an actual reproduction base.
First, the poured cast iron base is filed smooth by hand and given a series of four coats of epoxy paint (the type used for resurfacing bath tubs and sinks). There are two primer coats and two umber gray coats, with hand sanding in-between each coat. The pattern made from an original and the bases themselves were made in Portland, Oregon.
Instructions include showing how to remove the screw threaded bottom of the 44 microphone yoke and use the three removed screws to attach the yoke to this base.
There is also a reproduction RCA product label glued to the bottom. Three rubber feet, similar to the original metal and felt feet, which are no longer available, are mounted on the bottom. To safeguard selling these bases as original RCA products, the year of manufacture is embosed on the cast iron underneath the base. Otherwise, it has the RCA numbers embosed underneath.
This base is ideal for desk use or for displaying your 44 microphones.
There is also a reproduction RCA product label glued to the bottom. The original metal and felt feet are no longer available, so we have used rubber feet mounted on the bottom. To safeguard these bases being mistaken as original RCA products, the year of manufacture is embossed directly in the cast iron underneath the base.
ALSO AVAILABLE: Protective cloth zipper bags to protect the 44 mikes when not in use.
We sold many of these bases in the 2000s - if you are considering an original base by some vintage or antique dealer, be sure they are able to produce provenance.
