Alright, here are the pics. It was refinished at some point. Seems like a number of the Israeli guns went through that or further refurbishment during their service lives. Has an extended ambidextrous thumb safety, which is anachronous and possibly a replacement. The ring hammer is not normal on this production year, but from what I understand military and LE customers could still order it; same with the lanyard ring. I like the wooden stocks.
Some minor damage to the slide, nothing that will affect function. The bushing has a little nick in it as well (probably dropped at some point). Other than that, it's in pretty good shape. I'm wondering if the thumb safety was a different one; I could see whatever caused the damage to the slide also damaging the thumb safety, warranting replacement, in this case with a newer type of thumb safety.
Slide markings. No serial number present. If there was a serial number present and it was removed, whoever did the removal did an incredible job hiding the fact. The slide type is consistent with the date of manufacture of the frame. The last four digits of the frame serial number were electro penciled forward of the ejection port.
Barrel markings. Note that the barrel is a MkII type with the straight feed ramp. The MkII wasn't out yet in 1980. It could be a replacement. I've also read about there being some transitional Hi-Powers in the 1980s that have a mix of the Classic and MkII features. No serial number, as you can see, although there are some striations where it would normally go, so perhaps it was removed. Hard to say for sure. If it was removed, it looks pretty clean. There are similar striations elsewhere, so I can't be sure that it's a remnant of a serial number removal process. Last four digits of the frame serial number were electro penciled onto the barrel hood.
Bore condition. The imperfections are actually just dust. The bore is seriously very nice. The seller rated it below actual condition. If you look at it closely in the right light you might just barely notice striations from having been fired, but there is no frosting, pitting, damage, or scratching, nor are there imperfections otherwise.
The frame has Israeli police markings on the left side of the trigger guard and the FN crowned egg proof mark on the right side. Even though the serial number is present on the front strap of the frame, the last four digits were electro penciled onto the right side of the dust cover. At some point the Israelis drilled holes into the frame. I don't know what they are for. The one going through the trigger guard is probably 5mm wide and the ones on the dust cover are probably 4mm wide. They are not threaded at all and were drilled prior to refinishing. All I can think of is some kind of light, laser, or optic mount that bolts on, but I have yet to find any product that matches them. If they can't be used for anything, I'd like to have them filled, but it could be pricey. Cheapest option may be to have someone make plug screws and thread the holes to match, and then files the ends of the screws flush and refinish. I can live with the holes, though. I've seen them before on Israeli surplus Hi-Powers, but in topics on them no one can seem to figure out exactly what they are for. If anyone knows, I'd be very interested in finding that out.
