A Heavy Weight Crossbow

[CSinTX]

More than two years, and I have now caught covid for the first time. Not being one to just sit around, a couple motrin and out to take some pictures of a crossbow Ive had for a while. I dont know a lot about it except it's big and heavy.

I think for castle defense? Approximate age? Does anyone know of similar examples? Period art work?

What time period were the four pins used to secure the parts?

I think the string is likely a replacement?

What would the empty holes in the top be for?

Is the trigger in its original configuration or would it have been fired with a lever when first made?

Lots of pictures!

Thanks a bunch!
