Canvas tents have been around since before they started making tents out of nylon, polyester and other synthetic materials. I own two canvas tents myself, both a Kodiak and a Springbar.
From Wikipedia, the free encyclopedia. The conditional perfect is a grammatical construction that combines the conditional mood with perfect aspect. A typical example is the English would have written. The conditional perfect is used to refer to a hypothetical, usually counterfactual, event or circumstance placed in the past, contingent on some other circumstance (again normally counterfactual, and also usually placed in the past).
The conditional construction does not normally use will or would in if-clauses. EXCEPTION: If will or would express willingness, as in requests, they can be used in if-clauses. e.g. If you will come this way, the manager will see you now.
