On this side of the pond AYA's in the fifties where not that common the Spanish gun flood started in the sixties though I will say that AYA guns where far better mechanically than the rest of the other makes mechanisms that where made of toffee. Though I will say that the in letting in the stocks head AYA at the time did remove a lot of wood internally for some reason. I will say at that time AYA where the best of the bunch that I worked on, the rest went into the scrap bin over the preceding years well they where so cheap that it did not hurt anyone much in the pocket.
