Is retro cyclocross bikes a thing?

[pwebb]

... other mid school options exist too - the venerable surly crosscheck though a bit heavy and with comparitively relaxed geometry can turn its hand to a bit of entry level cyclocross - I have since made this one more 'gravel' spec but it was in a CX style before

I have a couple, but I guess the difference is that both of these would have been bespoke builds for a specific customer, rather than a production bike. I've got 28 tyres on the 90's Russell, but could probably get 32s on it. The '65 Roberts has 35c Tyres. Perhaps could get a little more, but wouldn't give much clearance on the rear.
