Dear Mark, I wouldn't use either the Taylor or the "bi-metallic" key in the Marlin daley, both are prone to breaking. The Taylor is a malleable cast iron key and the were supplied as blanks to locksmiths. These were thicker than the original keys as the cast metal would only pour in larger diameter moulds than the original size required. These keys need to be filed down to suit and depending on how acturately this was done, a lot of the strength could be lost by a misplaced file stroke. The bi-metallic key is usually made of zinc diecast ( for the intricate part of the key cast onto a steel frame which would include the key bow (head)Dominion and Unican still make bi metalic keys but I have not seen the Marlin, maybe another key blank supplier.

Zinc, like the cast iron is prone to facturing and fatigue from age.

I would only use steel keys as the original or
new investment cast steel keys that I make.

sorry no info on the dates for you.


The first one is marked "Taylor" and I know that to be an aftermarket key sold by locksmiths. The keys usually have to be filed down quite a bit to enter the lock and work properly. The second type key has no markings at all and has a thick bow (handle part of the key). The third type of key is stamped " on one side of the bow and the numbers "0656" usually on the other side of the bow. I have seen both stampings on the same side on a few examples. The bow is about 1/2 as thick as the type 2 key. I would like to know if this is an original key that was supplied with the cuffs or is another aftermarket key, like the Taylor. The key with no name seems to be manufactured to better specs than the other two. The bi-metallic key has some fine pits and does not look as nicely finished as the other. It does work very well, however. The Taylor version is by far the most crude and needs some filing to get it to work.

: Any help on my two questions would be very much appreciated. Thank you. Mark
