Thankyou for posting those pics!
That helps matters considerably!
Note that Excam was the original USA Importer for all TA90 Series Pistols.
Definitely a pre-series 88 model and made sometime in early 1987. It will use either pre-series 88 Tz75/TA90 Magazines or Pre-B Cz75 Magazines.
Note that there is a way to use more modern Cz75B Magazines in these Pistols, but requires a minor Frame Modification:
https://czfirearms.us/index.php?topic=39056.0Also note that the Pre-Series 88 Pistols were made with a softer grade of steel, having high Nickle Content, meant to prevent corrosion.
They will take a steady diet of standard pressure Ammunition fairly well, but use +P level Ammunition only sparingly.
Note that the Barrels are very well made and the Barrel Steel is much tougher than the Frame and Slide and will withstand +P pressures easily.
One common issue with the Pre-B Cz75's and Pre-Series 88 Tanfoglio Pistols is that the Front Slide Barrel Bushings come loose.
Simply Blue Loctite the Bushing back in and all will be well. I actually recommend it as preventative maintenance.
For many years I shot and carried a Pre-Series 88 Tz75, and it was a very good Pistol.
