Toys R Us!
"I don't wanna grow up, I'm a Toys R Us kid..." 
The 50's were a great time to be a kid...Mattell, Hubley, and
other toy makers were cranking out clones of TV show
guns...Mattell even came out with the innovative "Shootin' Shell Fanner 50" that actually shot plastic bullets via a spring-loaded cartridge...They had a snub-nosed companion revolver loosely based on the detective specials ...Also "Shootin' Shell"...
Hubley had a very realistic top-break revolver capgun...And a
lever action cap rifle that was chromed Zinc w/plastic furniture...
I had a Shootin' Shell Fanner 50 and the Hubley lever
action...But the
Mattel MMP was my prize...
Loosely based on the Mauser Broomhandle, but lots of obvious fantasy additions...and a belt clip on the stock-holster...Held a roll of caps and shot them off full-auto...
I don't recall where or how I got it, probably traded something
for it (trading was big in the 50's), but I do recall playing
with it in the snow...So maybe a Xmas present...
But while rolling down a snowbank, the MMP got caught and the barrel snapped off...I took it home, found a suitable dowel of some sort in my dad's 'stuff' drawers/boxes, and glued it back together...We had really good plastic glue back then; Testor's and Monogram both made good glue. Outlawed now, of course - dangerous inhalent...
But I glued it back together and it went on to play again...I
have no idea what ever happened to it...
About a year or two ago, there was a discussion here about toy guns...I remembered my MMP and went online to eBay and Searched for MMP's...They were selling at phenomenal prices!!! A hundred dollars and more!!!
Even the box the toy came in sells!!! I couldn't justify that...but I put in some lowball bids, and last week finally won...this...
It even has a Patent number...2729011...Patented in Jan
1956...(The patent pic actually shows a Thompson-style cap gun - it's the mechanism that got patented)...I was 6 then...I probably was 9 or 10 when I got my MMP...
I realize this has nothing whatsoever to do with this
Forum...just reliving some of my childhood memories...This was
one of my fondest toys...
This one has been neglected for decades; looks like it was never oiled (several labeled oil ports), but nothing seems
broken...just gummed up and erratic...
I don't even know if they still sell rols of caps...But this will
go in my [public] display case, along with my slide rule,
cigarette case lighters, and antique staplers...
