By the way, did it come with a magazine? Your pics don't have one so I have to wonder.
I had a bit of a time tracking down mags that will work with the short rail 75's. It has to be pre-b which is easiest to identify by the large groove at the base of the magazine, and possibly even engravings on the back or a stamp with a serial number. Back in the day, the short rails had stamped matching mags. But many had basic engravings of the last few digits of the serial scratched in. You can expect pre-b mags to run at least $100 these days, maybe even $200 if the seller has no soul. Weirdly hard to find considering these were not exactly scarce back in the day (I mean any pre-b 75 using the same mags)
But if you are intending to shoot, you should pick up a spare slide catch. They run about $50. I had to order from Estonia to get one because I don't want to risk breaking the original. You have original grips too. If you want to shoot it you may want to pick up some aftermarket grips as well.
You're in Canada, right? I only ask because the engravings are kind of up my alley. I am pretty interested in a short rail I can shoot without worry. Mine is pristine and it spooks me a bit to take it out at all and that's just not fun. But I have no idea how we would undergo a purchase or trade if we are in different countries. Import rules and all. I would never trade my pristine one, but I can find a fairly reasonable one and trade. I mean, if the stars align. There is one on gunbroker right now but 2k is a bit steep for one that worn down and with that high a serial number. $1200 maybe. But 2k is practically psychotic. In 5 years it might be a dream to find one for 2k but it's not exactly in my budget at the moment so I'll let that one go.
I'm not positive how the engravings affect things honestly. Yours is silver in color, likely because they stripped it to engrave and never re-blued it. Stainless, polished cz's can be pretty pricey even if modified. It wouldn't surprise me if yours retains its value because of the engravings. Harder to sell, and a narrower market, but still pretty desirable none the less, especially if it has the matching serialized mag and barrel.
Anyhow, I think it's awesome. You will likely find a similar opinion from pretty much everyone that sees it and knows what it is. Short rail is short rail, and one you can shoot without feeling guilty is almost better. If you shoot it, please post grouping pics. We're all about gun porn like that. I'll do the same at some point.
