Local shop, plus a #IS ignition simulator  also, going to need some work, a few capacitor replaced and thing need lube! I got the distributor hold clamp  working like it should, surface rust on the posts and the screw.Something not working can not upload pics, not the size of them they are jpg.

The error say the" attachments upload directory is not writable
your avatar or attachment can not be saved."
No idea what that means!

Me neither!! But I was able to open the link to your photos!!

I hope there wasn't too many pics? I usually take a bunch as other  may have one missing pcs or got it  as a pile of parts. Need to update the count, it's over 5,000 now. Not sure how many more I've tried to count them all but get sleepy .....

Looks like pics are working again!

Cool tool for sure.

The Sun distributor tester is the Holy Grail of auto equipment.

and I have very seldom seen the added piece.

Nice score.

I would not have hesitated to grab that.  Learned how to run one in school

I was in high school in 1973 we had one like this I don't remember the model. Then I found a Sun 404, the right after that I found a Allen. I liked the Allen better a sold the 404. Then came across a Sun DT-1, it works but  some of the gauges do not. The manometer has rusted up, down and all around?  This came along so it will look good with Sun 620 Gen/starter tester. It takes me awhile standing in front of them for it all to come back to me. But it's fun running and restoring old parts I just don't do a lot. otice I didn't mention engine analyzers, they are in the garage I have a few, the go to machine is a 1980's 1115 that I got in a post service auction. I do like well made in the USA tools and machines!

here's a Sun tester that you don't see that often.
