I have a Holland & Holland 500 BPE and I was hoping to get any info on the gun I can and also what you think the value might be. I have a letter from H & H dated 1984 that says they do not have any exact details on the gun but it is somewhere between 1879 and 1880. It is an underleaver gun and has Holland & Holland on each side behind the hammers. It has charge 4 1/4 drams case 3 inches on front of reciever. The serial # matches on bbl and reciver 5753 the other mark on botton of bbl is 39. The bore looks shiny with no pitting and rifling looks good. The bbl has no pitting anywhere but looks like it has been blued you can not see any damaskus which I assume it must be a damaskus bbl. The reciever is wore almost shiny with fine engraving but again no pitting or rust. The stock appears to be original with a few dings but not too bad. It has a wooden case which looks like quarter sawed oak with brass corners and velvet lined. the small doors on case appear to have ivry knobs. It has cleaning rod and attachments and 2 tools with it plus 2-5 round boxes of empty brass. Gun does not appear to be abused and is in excellent shape for its age.I will try to include some pictures. Any help would be greatly appreciated. Thanks Steve
