AB Charles was an institution back in the day. I still remember when my parents used to take me to their Dormont, PA location to pick out a few unusual items you couldn't find at the toy store. I distinctly recall peering through a glass case at Corgi tanks and trucks and cars... I still have the Batmobile and the Range Rover Emergency set. Probably other stuff too... Dinky, Britains, etc. <sigh> The good old days indeed!
They still had a decent inventory at their Banksville location; the train guy (Mike?) was pretty good as well. He disappeared eventually. They had an elaborate setup there, with two floors, a massive slot car setup, and a big RC area. For a while they were active on eBay, and they got into buying a lot of estate stuff and re-selling it. The owners lived out in the South Hills and often talked about moving out there because there was no Hobby Shop in the area other than Iron Horse (also a memory).
Their last location was literally at the bottom of my hill - I could walk to that plaza - my daughter frequently does (Yikes, now Bob knows where I live...). No one knew they wre there. The shop was an empty shell of what it once was, with a lot of pre-owned train stuff and such. They at one time had a few good O gauge engines (used); I still kick myself for not buying the Premier F7 ABA set they had for a steal. No new inventory to speak of; even their bins of Fastrack was largely pre-owned.
Nice guys, but they didn't understand the value of marketing, and they only scratched the surface of online sales. I remember telling one of the brothers that they could be relevant in the online hobby business, but got a line about "the other brother, blah blah blah...".
Shame to see them gone. I bought from them when I could and it was about as convenient as it gets, but with little to no inventory and a new, apathetic sales staff, I suppose it was inevitable.
