There really is no way to know by looking at him. The albino types can all look similar. However, If it were me I'd try a Rainwater (aka Las Vegas) albino first. The reason being that the Rainwater albino is the type most often associated with Redstripes.
Raining redstripes, as they are called, are common and you should be able to find a female easily enough. I have never heard of a Tremper Redstripe or Bell Redstripe although I'm sure they are out there.
And in any case, if you put him to a RR you will preserve the Redstripe trait and the resulting offspring will either be albino (if it's the right type) or they will be 100% het Rainwater (from the mother).
