The BP-1 utilized a unique "chassis", 1/2" pitch but smaller drivers more like the size of 3/8" pitch chain. There were three different versions, AR-8 is the "Auto Sharp" type chain with heavy cutters, AC-8 is the chipper type chain (in Rogers' photos above"), and A-8 also "Auto Sharp" type chain but with lighter stamped cutters.

This is A-8 type chain

This is AC-8

This is AR-8 with the heavy cutters and the drive sprocket peculiar to the "A" chassis.

I have a couple of short pieces of the AR-8 chain but have never seen a full loop of it anywhere.

For the record, that gold colored drive sprocket is standard 1/2" pitch and not the correct one for the AC-8 chain shown in the photos.

A BP-1 story I have is there is a small engine shop in my area that was a McCulloch dealer up unto the very end. The first time I went there looking for Mac parts they mentioned their BP-1 on display and asked if I had ever heard of one. When I replied "I've seen 2 racing each other", they were very surprised to say the least.
 
The old building had decent footings at one time and there was a short basement/crawl space on the west end of the building, but only dirt under the east end. At some point, someone dug a trench down the middle so they could run some drain lines when they added a bathroom on the east end.

The last bit of the building has been crunched up and scooped towards the west end so the contractor can dig it out with his grapple.

I see you've been looking at the threads Roland, when are you coming for a visit?

Haha, I peak in from time to time to see your museum grow and grow. Nice to see that you have expanded your interest to other brands than the famous yellow brand you started with. I still have 2 years to go at work and hopefully will be able to pay a visit to your homeland then. Wayne's chainsaw museum is on my bucket list and Iowa ist just around the corner I guess :omg: I'll let you know in time when to put the beer ready !
