Thought the group might enjoy this. Had some radiator shell problems; a broken fitting on one side and lost thimble on the other. I fixed the broken side by riveting an L shaped bracket of steel using cut off nails for rivets. Couldn't find a thimble in my box of old used parts. I just couldn't see spending $8 post for a $1.50 part and waiting for a new thimble from the suppliers ... so I cut the buggered end off the bottom of an old steel dope cup and it did the job.
Sorry for posting again ... didn't see the first one take.
Likely period correct.
