THANKS for the props, guys!
My old '64 Galaxie still carried its H&M tag as found. And so did the next car waiting in line in my shop which is Bobby Allison's 1968 H&M #29 Bondy Long Torino (Also FE powered: 427 8V TP).
Here is what those tags look like in detail:
I am very, very lucky in this regard since H&M tags often came adrift during combat/rebodying or became trophies for mechanics along the way. H&M VIN tags came into use in 1964 (late) after they team began to receive bodies in white from the Norfolk assembly line. Before that, H&M Galaxies were regular serialized cars (the '63s were "Q" codes while the '64s were "R" codes). My '64s tag, I believe, was installed at the end of the season when the car was sold to journey-man Grand National driver,Jabe Thomas after its H&M days were over.
There is a relatively new vintage racing group for drum brake stock cars out on the Left Coast. Those guys just had an event at Sears Point that was a lot of fun. A couple of my old cars were running in that group. It was a hoot!
(The '65 Galaxie is one of my old H&M cars. it is Chassis # C5HM-10047. It was cool to see the old girtl at speed. I only got to run her at Goodwood one year).
I think they will be running there again next year. Maybe Laguna Seca, too. Here is a link to their sithttp://www.historicgrandnational.com/cars.htm
As to the other teams and their "badging" practices: that varied. Stroppe built Mercs got small brass tags with unique numbers. Banjo Matthews (when he went into business) stamped serial numbers on the top of the right front frame rail. Other teams simply used a magic marker to jot a number down under the dash that quickly faded. So. documenting old stock cars can be tough. But it is FUN!
BTW, the Galaxie rolls on correct 15 x 8.5" H&M double centered rims and Firestone 800 stock car tires (29.5" tall/8" tread/10" section width).
