EOS-1 grips

I finally found a GR-E1 grip but I had to buy an EOS-1 with a BC error for $39.9 USD plus $29.99 USD shipping to get it. It actually turned out okay because I was able to get the EOS-1 working by using the Mirror Magnet tap trick.

Now I have the complete collection of grips:

Here is how to fix the mirror magnet BC Error: (fast forward to 8:39)

The only one I've had the problem with is my FD-mount Canon T90. Wonder if this works there?

After looking for the first time in a long time, found this for the T90

I know what you mean...waited more than a year to locate a GR-E1 grip on the marketplace sites. Got lucky last week since I did weekly checks.

It replaced the Power Drive Booster E1 that was missing its battery cartridge, which seems to be harder to locate than the grip. Now I am happy two two grips and two good PB-E1s for both of my Canon EOS 1s.

Yes, the the BM-E1 and BM-E2 battery magazines are also hard to find. I think it is because people leave them sitting around for months, and then the alkaline batteries leak, and the resulting corrosion damages the contacts.

How much did you pay for the GR-E1? I found the prices to be crazy?

My GR-E1 doesn't have the little grey tab at the top. It is the only one I have seen like this and at first I thought maybe the tab just fell off. But upon closer inspection I can see there is a design change and the grey tab version is quite different because there is a slot where it attaches, to allow the side to side movement.

The grey tab does seem to make it easier to flip out the battery.

The GR-E2 is quite different because it has a door which completely enclosed the 2CR5 battery.

Oops, I took too long editing my post and now the photos can't be seen.

Here are the photos I meant to include.

There was a store in the UK that had the BM-E1 in stock just before Covid-19 pandemic made a mess of things. I inquired about it around last August (I think) and they were out of stock then--I should have ordered it when I saw it. Hence, the hard lesson I learnt. {If I see one that is hard to locate and scarce and I find one--I JUMP on it immediately (if reasonably priced)}.
