There are a fair number of used pre-Bs out there. However, the small details represent large give-aways and thus, limit the pool of pre-Bs that can be used (abused?) to closely mimic a Short-Rail. The most obvious points include the Made in Czechoslovakia roll mark needs to be a one-line roll mark (available only up to 1983), more upswept front on the trigger guard (up to 1985), one-hole safety lever (1988-95 but then, the trigger spring hole is different on these), roll marks on the front of the left and right trigger guard (the latter is extremely limited to 1980 without the dimpled proof mark) and staked front sight. B models will not work due to the completely different slide markings and difficulty in hiding the firing pin block roll pin. Plus, manufacturing any new item with the old logo would require licensing (currently used by Luvo Arms).
