I got my FFL in 1987, still have it, now 07/02. I remember when the last ones came in (1988 I believe. the price actually went down. I bought a NIB 50.63 para for $875. still have it.
I had been wanting one for many years.
Had the 50:63, several 50:00's and built several Imbels. Wish I would have kept them. They were awesome rifles.
