Lol Ralph ive never heard of a coin op gas metre. but i wouldnt be surprised if Dan had an old coin op dopr from the toilets in melbourns cbd. I remember those from the OLD days. 
No I do t have one but its been on my wanted list for a long time..
I was watching a usa tv show the other day and there was a guy collecting and restoring old coin opp motel bed vibrators lol
some where pretty cool looking especially the old art deco ones.
that might be one collection the wife might like Dan
