I'd certainly give it a try - a float is a float after all. I'm sure it can be adapted if not a perfect match.

Especially onsidering the Morgan Spares sender is $145 exchange and the Melvyn Rutter one is £120 plus postage. The MR one also looks like a generic one, rather than specific to Morgan so there may be cheaper options out there.
