This wood base did not come with hinges AFAIK. At the time the base was built, the Duals (like 1019, 1209 models for instance) were distributed by United Audio and did not come with hinges (at least in the US anyway). At some point the base was built using similar materials with 90 degree angles; the lid had a tuck-under lip to hold the cover in upright position, the sides were walnut on MDF. After that, the base became a plastic frame with vinyl-wrap MDF parts and that was when real hinges were introduced.

But then I also saw 1228s with your base and small hinges (I've never had one like this), so it may be possible. Looks to me like the base was evolving about the time this model series of turntables were being shipped to N. America. The Canada base units were generally better looking and built better, and they were all provided by the distributors up to a certain point and If I have it right Dual took over at some point during the style changes.
That base evolved to an injection plastic version (no MDF) with wood-grain vinyl appliques. This type of tapered base (yours, pictured) had molded lift-off dust covers and MDF+ real walnut veneer wood construction. I don't know if Pats hinges could be adapted to this base or not. Your dust cover appears to be in great condition, don't risk damaging it.

Steuerpimpel, Control nipple stud, Guide (and sometimes it's not even listed or numbered) -- Whatever name for them is found in the factory Service Manual; old worn and cracked ones can rub tonearms just half-way. Or, not at all. Keep 'em guiding and gliding.
