Buckle Guns, Mattel made them , They made the "Spitt'n' Image carbine , Fanner Fifty & the Shoot'n' Shell revolvers Ed speaks of...
Greenie Stick'um Caps were their patent as well...
There also a Roll'n' Block (Remington) single shot carbine...
This was the Golden age in toy guns , NICHOLS ,Hubley & Marx were major players too a that time.
In that era , No orange muzzle tips .... Good Lord , a kid could go around well heeled , walk into a corner Mom & Pop store without a second thought or raised eyebrow.
Those guns, command , BIG money to collectors today...Note the $8.00 on the original box set .... about $250 today.
As to Leather quality the best I recall was, my Paladin Rig. A single rig in good sewn top grain leather, and a Knight chess piece in chrome plated metal.
