see the link too see what monster drop what clues. Level 21 guards are the lowest level NPC to drop them. For higher levelled players, Level 83 Cockroach soldiers found in the Stronghold of Player Safety can also be slain for level 2 Clue scrolls. A monster found to have a fairly high drop rate of these scrolls is the pyrefiend. i have also found that dagannoths under the lighthouse which requires completion of horror from the deep drop a clue very frequently
No they do not drop dragon scimatars because even a rune scimitar is considered a rare drop from a cockarach monster and dragon scimitars are "MEMBERS ONLY" item.

The best way to get 60 attack is to probably train on cockroach soldiers (lv 83). not only that, they drop rune scimitars, rune square shields, laws, deaths, and lots of other cool stuff.
There are only a few. The best drop is the adamant med helm so this is not recommended. Attacking Cockroach Soldiers are better as they drop Rune Scimitars and Sq. Shields. Note: It may take about 15 kills to get a good item. Most of the time the drops are coins.
You can make one, at a high smithing level (not recommended, since you lose money on most smithing activities). Also (from runescape.wikia.com): "Free players are able to obtain the rune scimitar as a semi-rare drop from Cockroach soldiers in the Stronghold of Player Safety. For members, the rune scimitar can be obtained as a fairly common drop by a variety of monsters, such as Zamorak warriors and Fire giants."So, it seems that for free players, the cockroach soldier is your only option. Of course, you can simply buy one at the Grand Exchange.
Cockroach Soldiers drop a wide variety of items in RuneScape and have since been less killed as a better alternative, Grotworms, has opened up after a recent update. Cockroach Soldiers now always drop Carapace, which can be crafted for crafting experience. Cockroach Soldiers do have access to the rare drop tables, but offer fairly invaluable regular drop items and therefore are not killed as commonly any more due to newer and better monsters.
the drop rate is on chance but i belive it is a rare drop from them
considering anchous can weaken you and i forget they might be aggressive i would go with cockroach soldiers and plus cockroach soldiers can drop rune scimitar witch sell for around 30k right now.
