That is a factory RPB wooden buttstock,
Fairly early. Earlier examples had only one notch on the legs from what I’ve seen and sharper contours. Later examples from SWD had both legs notched and the Cobray trademark stamped on the tang and rounder contours. Some examples had the Cobray stamp on the butt end, some did not. It’s a crap shoot. Some even had the logo stamped on the side (very rare)
They are going for around $150-250 nowadays, they were selling for more a year or 2 ago but the craze Seems to have died down a lot on GB and they have become harder to get rid of and don’t fetch top dollar like they were a year or 2 ago.
These stocks were introduced by RPB in 1979, advertised as their own design. There is what I believe to be a prototype version of it displayed on the cover of the RPB catalogs, I also have a copy of a Polaroid photo from Wayne Daniel’s photo album that shows the same oddball prototype stock with the large logo on the side and slightly different profile than the production units. I have never seen one of that shape in the wild. The stock advertised for sale in the same catalogs has the standard production profile.
The stocks came as a factory option on the RPB “deluxe” carbine with a wooden forend, and they were sold on their own as an aftermarket upgrade as well.
Prototype style stock.
Deluxe carbine

Early Sharp contoured RPB stock (like yours)
Slightly later example with rounder edges and Cobray marking on butt
M11 version. This example came from SWD.
Another SWD unit with Cobray trademark on the tang

Thanks Mitch for all the photos. They really show the progression of the stock.
I’ve had the Mac (PS with a ‘73 date) for a few years. It came with the optional wood butt stock and an assortment of 30 round magazines - a couple blued and a couple with a parkerized type finish.

Cool manuals ya got there too. Fred Rexer and Euclid Sales. I’ve got those in my collection. The Euclid manual should have a price list in the back of accessories from RPB circa 1980 or so. The wood stock is listed in the price list.
I’ve got that red white and black MAC brochure in a frame on the wall in my office as well as an identical one for the M11 .380
most of the 30rd mags were surplus m3 grease gun mags that were either factory or aftermarket modified for the M10… 1/16th of an inch milled off the rear where the mag catch engages the magazine, and 1/16th off the mag stops on some of them. They came in blue and parked finished as you suggested, the vast majority of the factory MAC magazines were blue steel, with the USGI contract SPW or GL markings, stamped by MAC with a small Cobray logo with MAC above it and a number below it, usually 6, or 4 but there’s other numbers as well.
MAC offered a wood stock as well for the M10, but it was not the unique shape of the RPB stock. The MAC wood stock was a Thompson SMG stock that had been chopped down.
They also had an M11 stock that was a weird skinny long ordeal, very strange looking… I’ll have to try to find a picture, I have one somewhere.

Thanks for the rundown on the magazines. I’ll dig mine out and start another thread on magazines. I’ve read through some old postings on the mags but still not sure what I have.
A few are marked with Sparks-Withington initials but I don’t remember seeing a Cobray logo on them.

there are plenty of magazines out there that are just normal surplus M3 mags that have been aftermarket converted to M10 spec. Especially nowadays it’s a lot more economical to just get a $30-$40 surplus m3
Magazine and file a little off the backplate than spend over $100 on a factory MAC magazine.
I’ve got plenty of info and pictures on the magazines, happy to share if you start a magazine thread. I highly recommend picking up a copy of “THE MACMAN” by Frank Iannamico. That book is the “Bible” for MAC enthusiasts, beautifully illustrated and the price is outrageously low given the wealth of information provided and how nicely presented it is.
