I put this together about 5 years ago and remember having all the pieces. For this listing, I made groups of 10 until I had 100, then wrote it down and threw them in a ziploc before counting out the next set of 100 pieces. Some pieces were still connected to others. I ended up counting 1,098 / 1,100, so it appears to be short two pieces. I could have miscounted, but I’d rather not bank on that in the case I counted correctly, therefore it’s 99.8% complete to my knowledge. Unsure which two pieces are missing if so.
